Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

Hola, gente bonita 🫶 Lass uns ein Bier trinken, Spanisch-Deutsch sprechen und eine gute Zeit genießen! Grundlegende (oder bessere 😛) Kenntnisse in Spanisch oder Deutsch sind alles, was du brauchst. Vamos a tomar una cerveza, hablar español-alemán y pasarla bien! Un nivel básico (o mejor 😛) de español o alemán es lo único que necesitas.

We are inviting you to our next Evening of Meditation on **Sunday, the 5th of April**. These gatherings are not just about meditating on your own, but a step inward that we take together regarding a particular topic. This time we explore **The key to experiencing our interconnectedness with nature**. Most of us live in cities, spending our days in front of screens or in closed environments, and only occasionally take a walk in a park or go on a hike. Our experience of nature is often limited to a little time off to "recharge our batteries," when in fact, a deeper connection with nature can open up so much more within us. Let’s discover The key to experiencing our interconnectedness with nature. 📍Where: [Yoga Sky](https://maps.app.goo.gl/kBxUvZrqo5yzRNe88?g_st=ipc), Am Tempelhofer Berg 7d, 10965 Berlin Follow the Yoga Sky signs in the yard, and take the elevator to the top floor. 🗓 When: Sunday, 5th of April, 19:00 - 20:30 Please arrive 5-10 min earlier to settle down. 🎟️ Entry: €5, just to pay for the space (in cash or PayPal) For more info go to: [https://onenessberlin.com/](https://onenessberlin.com/) You’re welcome, no matter your background or experience. This is what has worked for us over many years and we love to share it with you. Looking forward to see you, Oneness Berlin Florian, Jazgul & Carla

\*\*\*\*\*\* ***For address and more details see the website www.pausify.org*** \*\*\*\*\*\* **Event Info:** Bring along your **current book to read** (or something **creative** to work on ) and join us for this mix of a shared focus time + discussion. \- 11:00\-11:30 \- Meet & greet \- 11:30\-12:30 \- Silent focus time \- 12:30 \- Discussion of books/ projects over coffee \(**Drinks & snacks are included** ☕️) Afterwards, join for lunch if you'd like (optional). * **To reserve your place, a ticket (€9,90/event) or a community pass (only €19,90/MONTH) [from the website ](https://pausify.org/)*www.pausify.org* is required** * **Attendance here doesn’t show sign-ups from other platforms. We usually have about 50 to 100 people at each event.** ***FAQ: Why does it cost money if I bring my own project?*** Because we rent a beautiful, central space for every event. Ever thought your monthly apartment rent was too high? Well, multiply that – that’s what commercial spaces in big cities like Berlin cost *per hour*. Of course, if all you want is just some quiet time, your home or a library is perfect. But if you’d like to focus & connect with others in an inspiring space – with drinks, snacks included – that’s what your ticket helps to cover. See pics from our events below - and on our Instagram: **[@Pausify (Co-Reading Space)](https://www.instagram.com/pausify_org/) ☕️** **[Pausify Co-Reading Space Website](https://pausify.org/) www.pausify.org** For questions, please contact us over [Website ](https://pausify.org/) www.pausify.org as this platform can have issues.

# **Das Treffen ist offen für w/m/d Personen.** Die Selbsthilfegruppe Berlin Prenzlauer Berg findet diesmal ausnahmsweise am Sonntag von 16:00 bis 18:00 statt. Zum Thema: **„Ja“ zu mir selbst – Die Kunst, freundlich „Nein“ zu sagen** Fällt es dir manchmal leichter, anderen einen Gefallen zu tun, als auf deine eigenen Grenzen zu achten? Oft sagen wir „Ja“, um niemanden zu enttäuschen – und zahlen am Ende mit unserer eigenen Energie. In unseren zwei Stunden wollen wir gemeinsam herausfinden, warum uns ein „Nein“ oft so schwerfällt und wie wir es lernen können, ohne schlechtes Gewissen Grenzen zu setzen. Wir arbeiten lösungsorientiert, wertschätzend und mit einer Prise Leichtigkeit. Du gehst nicht nur mit neuem Wissen, sondern mit konkreten „Micro-Skills“ für deinen Alltag nach Hause.

Hi, This is Sagar here. This is my first ever group and just the second event. The point is: to come open-minded and look forward to meet some Berliners interested to learn, grow and build. Or help others to Learn, grow and build. As I said earlier, I am someone with an itch to get into entrepreneurship, but lacking the exact directions, and failing myself in some of the very basic things. I am sure there are many, sailing in the same ship. Building a business needs a bit of everything : Digital literacy, knowledge of the bureaucracy, taxation, network building, social media skills, Tech- aptitude, AI-competence and what not. Lets meet and find out who can help whom with what. At the end, there is nothing to lose. We all will make friends and learn a thing or two. Cheers.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
