Bringt gute Laune, schönes Wetter und Interesse mit. Wir treffen uns je nach Tour an unterschiedlichen Orten. Am 1. April 2018 um 15 Uhr gehts los am Eingang zur Akademie der Künste am Pariser Platz neben dem Brandenburger Tor.

Viele Männer funktionieren gut. Im Job, in der Beziehung, im Alltag. Aber irgendwann kommt dieses Gefühl: Das hier bin nicht wirklich ich. Nicht unbedingt als großer Knall. Eher als leises Unbehagen. Das Gefühl, dass mehr in dir steckt, als du bisher gelebt hast, und du noch nie wirklich den Raum hattest, dieser Frage ehrlich nachzugehen. Genau dafür ist dieser Workshop. Du arbeitest in Übungen, die dir zeigen, was du über dich selbst bereits weißt, aber noch nicht siehst. Du sprichst mit anderen Männern, die sich dieselben Fragen stellen. Was du dabei entdeckst, lässt sich schwer in Worte fassen. Für Männer, die anfangen hinzuschauen. Die nicht mehr jeden unbequemen Gedanken wegdrücken wollen. Die bereit sind, sich selbst eine ehrliche Antwort zu geben. Du brauchst keine Vorerfahrung. Keine bestimmte Lebenssituation. Nur die Bereitschaft, für drei Stunden wirklich da zu sein. \-\-\- Das Event wird in Deutsch gehalten. \-\-\- **Praktische Infos** * **Ort:** HeileHaus e.V., Waldemarstraße 36, 10999 Berlin * **Uhrzeit:** 11:00 – 14:00 Uhr * **Dauer:** ca. 3 Stunden * **Eintritt:** 10 € (Barzahlung oder PayPal vor Ort) * **Teilnehmerzahl:** Plätze sind begrenzt. 6-14 Männer.

**Read the full description for all info.** Do you need a break from this noisy, fast-paced and, at the moment, very overwhelming world? Then you’re very welcome to join the Soul Care Circle. A space where you can simply be yourself, amongst people who focus on inner growth, mindfulness and genuine connection. Here, together, we create a safe space for meaningful encounters. It’s all about genuine connection, deep conversations, self-reflection and the joy of being together. **Among other things, you can look forward to:** * Sharing Circles, where you can express yourself authentically * Authentic Games, which playfully foster connection * Guided meditations or trance states for deeper insights * Mindfulness exercises that bring you into the here and now Over a cup of tea, you can settle in peacefully, take a deep breath and chat with others. Everything is allowed, nothing is a must, you set your own pace. Every event is designed and mindfully facilitated by me, Isabel. The Soul Care Circle has been running for almost 4 years, and I have been holding spaces for groups for over 10 years – always with the aim of creating places where growth, healing and self-expression are possible. Each circle emerges in the moment. The content isn’t fixed, but adapts to what’s present and needed at that moment. This creates a vibrant, intuitive space that meets you exactly where you are right now. **💌 RSVP on Meetup does not secure your seat!** **Please register via Whatsapp/Telegram: +49 (0) 1573 72 48 15 7** **or Email: wildandsilent.berlin@gmail.com** **📍 Location: Samariter Kiez (you will receive the address after registration)** **💫 Energy Exchange: €20 - €40 (you decide what to give)** **⏰ Doors open 5:45 PM.

Do you want to start building AI agents, but never had a chance to start? Are you an experienced agent builder and you want to test your skills in a fun environment? Are you a non-technical person who wants to get a taste of building AI agents? Are you an AI agent? Then come and let’s have some fun. **Format** We will have an AI agent competition. We will build agents and let them compete in how fast they can escape from a dungeon with challenges! Never built agents before? Don't worry, we'll provide a template of an agent. Not a technical person? Don't worry, we'll provide a visual agent builder (you can build agents from your smartphone) There will be 2 leagues: * Beginners: no skills of agent building or software engineering needed - you will only need a smartphone. * Advanced: bring your laptop with your favorite agent development tools **Prerequisites**: * **a Google account** (to sign in into the competition platform) * **readiness to spend ca. 5-10 EUR on OpenRouter API credits** (unless you already have a subscription to some LLM provider allowing API usage) * **(optional) laptop with your preferred development environment for building agents** (alternatively you can use a web-based agent builder from your smartphone, but it only allows relatively simple agent configurations)

Meet, Match, MoveOn and Manage or Master Why Meet 1)Meet new People Culture Languages. 2)Not Match Romance, Political Views nor Religion, only Respect and Joy 3) Moveon, advance with your level, goals, and especially share and try Rotate the groups and let others participate a bit. 4) Master the challenges, and Manage to give a Like or appreciate the meetups!! **Thematic** or small Concept: Manage to Bring 2 German Friends and you get a Drink. if you bring your Ex Partner + 2 German friends =2 drinks = thats the Challenge and the Attitude of 2026

Bring whatever you need to enjoy the park: food, drinks, sun protection, picnic blanket or anything else. The activities are free, yet you are welcome to throw some coin his way afterwards (his phone was stolen a few days ago and he would appreciate it). We meet in the south part of park Hasenheide, near the calisthenics area and Cafe Hasenschänke (which I've been told has free restrooms).

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

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. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in 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 Dianetics & Scientology life improvement center.
