Back in August, we explored how Design Thinking can help us uncover and validate the right problems. But even when we agree on what to build, things often go wrong, not because of bad solutions, but because we don’t fully understand what the problem actually means in practice. In this session, we’ll build on that idea and focus on the next step: turning vague ideas into something concrete, shared, and testable. Using Example Mapping - a lightweight technique from Behaviour-Driven Development (BDD) - we’ll work in small groups to: * Break down a feature into rules, examples, and questions * Surface hidden assumptions and edge cases * Align on what the behaviour of a system should actually look like If the previous session was about finding the right problem, this one is about understanding it well enough to build it right. This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

OBS! Normally these events take place on the FIRST THURSDAY OF THE MONTH, however due to Easter we will be hosting it on the SECOND THURSDAY of the month this time. **Meaning, the event will be on the 9th of April instead of the 2nd.** Nico Caramella breaks down the strategy of placing sponsored "best X" articles on high-authority third-party publishers. Join us on April 9th, for an exciting and highly relevant session! For anyone looking to expand their knowledge on how to get noticed and build their presence in AI-recommendations , this will be an important one to attend. The session will be held at the **Buzzmatic Office, Schönhauser Allee 149**, from **9:30 to 11:00**. Enjoy **free attendance,** some lovely **breakfast** and great conversation! Nicolas Caramella, CEO and Founder of [GetCited.de](http://getcited.de/ "http://getcited.de/"), will come to the Buzzmatic office and do a session on How "Best X" Advertorials Get Your Brand Recommended by AI. *Nearly half of every AI answer about software, products, or services traces back to one content format: "Best X comparison listicles". In this session, Nico breaks down the strategy of placing sponsored "best X" articles on high-authority third-party publishers to systematically build brand presence in AI-generated recommendations. Whether you do this for clients or want to understand the emerging discipline of AI visibility, this talk gives you the framework and the data.* In May we will be welcoming Andrés Tapia as our next external speaker, to do some deepdives on related topics. We will be posting more about this soon, so stay tuned! Bring yourself, a good mood and any thoughts or questions you have on the subject. We look forward to seeing you there and hearing your thoughts!

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. 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 sponsored the Dianetics & Scientology Self-Improvement Center.

Do you want more motivation and confidence to build Lasting Relationships? This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? 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: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & 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 class is held at the Dianetics and Scientology Life Improvement Center.

Perhaps you get weighed down with negative emotions you can't seem to shrug off. Or find yourself doing strange and irrational things - not really being yourself. We will cover why that is and tools that work to help you unearth your self, your self-confidence and motivation. This meeting will help you learn about how to effectively overcome: -Out-of-control unwanted emotions -Low self-esteem -Anxiety -Negativity -Stress -Irrational fears -Traumatic or painfully emotional incidents -Breakups -Betrayals -Feeling like you're not really yourself -Self-doubt...

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.
