The Cash-Flow Breakfast Club is NOT just a meet up. It’s the most unique Real Estate Investor Community of Mentors, Coaches & Masterminds. A community of growth oriented, abundance mindset, go-giver individuals with a BARE MINIMUM commitment to become financially free through real estate investing.
We focus on providing education and building networks to help every member solve their cash-flow freedom equation, so they can have the time-freedom needed to follow their passions, make a lasting impact and even change the world! The unique format of this event, which consists of high-level education, gamified networking, mastermind breakout sessions, case studies, group deal analysis, market deep dives, and peer-to-peer coaching facilitation makes this the most impactful local real estate investor group a real estate investor can be a part of.
The foundation of the group is built around the belief that everyone in the room has the potential to change the world… however most of us never have the time, energy or financial situation to even dare to dream big enough. Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom. Once that happens it is usually much easier for us to think bigger, dream bigger, be bigger.

Think With Ink™ - Lizard Brain’s visual facilitation workshop
**Just discounted: $500 off!**
**Register at** [https://www.lizardbrain.com/thinkwithink](https://www.lizardbrain.com/thinkwithink)
Think With Ink™ is Lizard Brain’s 3-day premiere graphic facilitation workshop. This is an intensive workshop that covers the essentials of using visuals to facilitate a group process.
The workshop covers three areas:
* Technique: Markers, paper handling, color use, lettering, drawing, forms, levels of information, listening for synthesis.
* Models, Methods, and Tools: visual energizers and icebreakers, meeting principles and ground rules, and visual tools for brainstorming ideas, comparing ideas, and collaboratively deciding the way forward.
* Experiential Practice: hands-on practice designing and leading facilitated modalities.
This workshop is meant for:
* The facilitator who wants to build a repertoire of visual tools,
* The graphic recorder or sketchnoter who wants to expand into graphic facilitation,
* The team member who wants to bring visual, participatory methods to the team,
* The consultant and coach who wants to help clients think through problems in a visual manner, or
* The visual thinker, the whiteboard salesman, the data visualizer, or anyone that sits in the intersection of visuals and helping others solve problems.
Each participant will receive:
* Textbook
* Sketchbook and sketchnoting materials
* Handouts summarizing key practices
* Set of markers
* Roll of twenty-five-yard paper
* This hands-on, practice-driven workshop will give you everything you need to graphically facilitate groups through the toughest challenges.
**The next in-person running is in Reston, Virginia, June 17-19, 2026.**

**FAQs**
* *Will this teach me to graphic record?*
* Graphic recording is large-scale visual notetaking for groups. Graphic facilitation is using visuals to help move a group through a process. Although you can apply many of the graphic facilitation methods in Think With Ink to graphic recording, we will focus on visual group processes rather than on the aesthetic side of graphic recording.
*
* *Will this teach me to graphic facilitate?*
* Yes!

What Is Progress? Knowledge Aggregation, Living Textbooks, and the Automation
Title: What Is Progress? Knowledge Aggregation, Living Textbooks, and the Automation of Scientific Discovery
Date: June 20 2026 Noon - 14:00 EDT
Summary: Our collective knowledge infrastructure — the textbooks, professional training resources, and literature syntheses that define what professionals across disciplines believe to be true — is quietly accruing a structural liability. Compounded confirmation bias, stacked citation-by-citation into the foundations of formal knowledge, means that breakthroughs can take decades to reach the classrooms, clinical workflows, and decision-making frameworks where they matter most. Meanwhile, the deepest friction is rarely acknowledged: before any field can build meaningful consensus on "why" or "how" a phenomenon occurs, it must first establish honest, consolidated agreement on "what" has actually been observed. That prior step is routinely skipped, assumed, or fragmented across siloed literatures that never cross-pollinate.
This talk introduces a framework called "Knowledge Aggregation" — with two distinct but complementary ambitions. The first is descriptive transparency: algorithmically mapping what has been said, measured, and documented across a problem space, without imposing causal interpretation or narrative. The second traces the boundary between empirical observation and explanatory claim, building systems that can separate the "what" from the "why/how" — because consensus on mechanism cannot be meaningfully constructed until consensus on phenomenon is first established.
Both ambitions are now within reach. By composing tools already at our disposal — large language models, classical NLP pipelines, public data repositories, and engineering-grade automation frameworks — it becomes possible to model knowledge itself, rather than merely imitate individual experts. One concrete expression of this is automating the writing of living textbooks: compressing the lag from bleeding-edge discovery, through replicated evidence, all the way to professional training resources. But the deeper aspiration reaches further — toward automating the discovery of scientific insights that have never previously been conceived, by systematically surfacing hypothesis combinations that no single siloed researcher would have had the cross-disciplinary vantage point to even ask. Drawing on ongoing systems biology and computational research — with ME/CFS research demoed as a use case for what siloed, fragmented knowledge infrastructure costs in practice — this talk maps the conceptual architecture, the real-world friction, and the data science toolkit for building it.
Speaker: As a systems biologist at heart, Sam specializes his biomedical research on interactions and connections in biology - rather than just one domain of expertise. He wears many hats and collects skill sets across disciplines, with degree studies and industry experience acquired across Chemical Engineering (BSc), Bioinformatics (MSc), Systems and Synthetic Biology (M2), Biomedical Sciences (MSc), and beyond. Even more important to him than niches or fields of work, comes down to the synergistic approaches that allow us to move beyond reductionism. The notion that a question can only allow for one answer, is inherently reductionist. By resisting many norms in science and engineering which can get overly reductive, his current role as Principal Investigator of Research for DMV Petri Dish (501(c)(3) non-profit local to the DMV region) embraces computational frameworks that aide scale-up and automation - not only around the processes which already exist with established workflows, but also taking a keen interest in attempting and accomplishing ambitions which have never been perceived to be possible previously. Sam carries a passion for the synergy of computational biology - fused with wet lab validation. This way, one can build a beautiful knowledge base in the theoretical sense, and then test to see if said computational prediction might actually be able to stand in the real world with wet lab validation. Translational modeling starts to become possible once biological experiment design can be iteratively looped alongside computational model design, optimization, and analysis - empowering the design of a better wet lab experiment, followed by a better computational model, back and forth until science is done!

A Poetry Workshop
Hey Poetry Lovers!
This group is on a roll. Here’s the gist:
We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week.
For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form).
Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.)
We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions.
Finally, if you plan on sharing a poem, consider how you will do so. Some options include:
* Print 5-10 copies to distribute in person
* Take and share screenshots in the Discord chat.
* Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat.
Most importantly, we’re excited to meet you!
Catch you on Saturday,
Diego / Ian / Cayden / Nate / Otasha / Lia / An

No awkward networking. No cliques. No dress code. Just great food, easy conversation, and people who will absolutely order the thing they’ve never heard of.
What we do:
• Monthly group dinners across D.C., Arlington, and Northern Virginia
• Cuisines from all over — we go everywhere and try everything
• Occasional food crawls, market visits, and cooking nights
• A welcoming mix of regulars and newcomers every time
Whether you’re a serious foodie or just someone tired of eating alone — pull up a chair. The more the merrier, and the table’s always big enough.
Who joins us: Food lovers, solo diners looking for community, couples, transplants exploring the city, and anyone who believes the best part of a meal is who you share it with.
Come hungry. Leave with new favorites and new friends. 🥂

AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge.
This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow.
Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required.
🛠️ What to Bring
Laptop: Fully charged and ready to go.
AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!)
🍕 Logistics & Perks
Food & Drink: Pizza and drinks provided!

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
