Free in-person event: Take Control of Your Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself.
Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went?
Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence?
Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

————————————
Engaging in men’s work is the new way to forge friendships while being open-minded to personal growth. Many men experience healthier relationships, personally and professionally, by engaging in this work.
Open Men’s Group is a container for men to share vulnerably without receiving judgment or feedback.
We believe that emotionally mature, powerful, compassionate, and purpose-driven men will help heal some of society’s deepest wounds. We support the powerful brilliance of men and we are willing to look at, and take full responsibility for, the pain we are also capable of creating – and suffering. We care deeply about men, our families, communities, and the planet.

Stop Guessing: A Product Person's Guide to AI Adoption
## 🤝 Host Information
A co-hosted event by ProductTank Columbus & Women in Product Columbus
💡 About the Workshop
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!
Parking: Plenty of free spaces available on-site.

Take Control Of Your Life, Freedom From Negative Thoughts & Irrational Emotions
Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences.
Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future.
What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs.
At this free local Meetup event we will talk about:
* What causes grief, anxiety and depression to become chronic.
* Is it possible to regain your joy and happiness even after traumatic experiences?
* How to break away from negativity and focus on the future
* What are the steps to take to get control of your mind and your emotions?
Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home.
Let's explore safe, effective solutions for healing from traumatic experiences.
Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there.
This group is sponsored by the Dianetics & Scientology Life Improvement Center.
