Have you seen the movie “**The AI Doc**: Or How I Became an Apocaloptimist” and are left with questions and thoughts that you're longing to express? A group of friends went to see this documentary and couldn’t stop thinking or discussing about it. Now we want to hear from more people who have seen the movie! Come share your thoughts about AI and the world. **NOT from a technological perspective but where our future lies ahead**. We will start from the key **questions** asked in the documentary, including but not limited to: \- Is it the worst or best time to be born now\, at the age of AI? \- Are you an apocaloptimist or pessimist? \- Did anything in the film challenge your previous beliefs about AI? \- Do you think AI will reduce or worsen inequality? \- What can we\, as the general public\, do to ensure AI safety? 💡Disclaimer: We aim to create a thoughtful, open, and respectful space for sharing ideas. You may encounter perspectives that differ from your own—and that’s part of what makes these conversations meaningful. Sometimes, it’s through contrasting viewpoints that the most interesting insights emerge. We encourage everyone to listen with curiosity and engage with respect. 📍We'll be meeting at Conference Room 2 at West End Library near Foggy Bottom.

This is a VIRTUAL FREE event every week. To get access details please [click here](https://www.eventbrite.com/e/the-recharge-fill-up-sis-tickets-1984961497272?aff=oddtdtcreator) If you’ve been pouring into everyone else and quietly running on empty… this space was created for you. There comes a moment in a woman’s life when she realizes she has been pouring into everyone and everything else… while quietly running on empty. The responsibilities. The expectations. The emotional labor. And somewhere in the middle of holding it all together, she forgets what it feels like to be **fully supported, fully resourced, and fully seen**. **The Recharge: Fill Up Sis** is **a sacred weekly virtual meetup** created for women who are ready to pause, recalibrate their energy, and reconnect with themselves in powerful community. This is not a motivational talk. This is not surface-level inspiration. This is a room where women gather to **release what they’ve been carrying, restore their energy, and remember the power of being in [intentional sisterhood](https://thewombsauna.com/wcoe "https://thewombsauna.com/wcoe").** ## What Happens in The Recharge? Each session is a guided experience where women come together to: * **Release** stress, emotional weight, and the pressure of carrying everything alone * **Restore** their energy through meaningful conversation, reflection, and grounding practices * **Rise** into clarity about what their next level of life and leadership requires * **Radiate** with renewed confidence, alignment, and direction This space allows you to experience the tone, leadership, and sisterhood that define the deeper work we do together. ## The Integration Lab: Where Knowledge Becomes Embodiment Many women spend years gathering wisdom. Books. Podcasts. Workshops. Spiritual insight. Therapy. Coaching. At a certain point, the question is no longer: **“What else do I need to learn?”** The real question becomes: **“Where am I actually practicing the life I say I want?”** The **Integration Lab** is the weekly coaching and practice space inside our **[1-Year Self Development Program](thewombsauna.com/programs)**. It is where women stop circulating knowledge and begin **embodying it**. Inside the Lab, we work in real time with the patterns, decisions, emotions, and relationships shaping your life right now. Awareness becomes action. Insight becomes discipline. And personal growth becomes a lived lifestyle. Women gather weekly to: * apply what they know to real-life challenges * strengthen emotional regulation and self-leadership * practice accountability in sacred sisterhood * build the consistency required to live differently This is not a space for passive listening. It is a space for **active personal development and sacred community life.** ## Who This Space Is For? This gathering is for women who: * are tired of carrying everything alone * know they are capable of more but feel stretched thin * value personal development and emotional growth * desire a circle of women who are serious about their evolution * are exploring whether they are ready to invest in a **year of intentional growth** Many women who attend **The Recharge** are preparing themselves to decide whether they are ready to step into the deeper commitment of the **[1-Year Self Development Program](https://thewombsauna.com/programs "https://thewombsauna.com/programs")**. ## What You Should Know This experience is **free**, but it is intentional. Women who attend are often exploring what it would look like to: * prioritize their personal development * practice emotional and spiritual growth consistently * participate in a high-level community of women committed to living consciously Come with curiosity. Come with honesty. Come with the willingness to pour back into yourself. ## Hosted By ## **[Thema Azize Serwa](https://thewombsauna.com/thema "https://thewombsauna.com/thema")** Founder of **[The Womb Sauna](https://thewombsauna.com/ "https://thewombsauna.com")** and creator of transformational spaces where women gather to **release, restore, rise, and radiate**. After overcoming eight years of infertility and PCOS, Thema devoted her life to helping women reconnect with their bodies, their emotional wisdom, and the sacred power of intentional community. Through her work in womb wellness, self-development, and spiritual leadership, she has guided women around the world in creating lives that are rooted in clarity, healing, and self-mastery. ## Final Invitation If you’ve been gathering insight for years but feel ready to start **living differently**, this space will resonate deeply. Because transformation does not happen through inspiration alone. It happens through **consistent practice, honest reflection, and community that supports your evolution.** **Come recharge.**

D.C.'s tourist buses ply a small, predictable circle around the monumental downtown. D.C.'s Metrobuses, on the other hand, make a dramatic sweep around the whole city. Join us for the better of the two rides! We'll start at beautiful transit hub Union Station, take the D80 up to Tenleytown in Upper Northwest; then the crosstown C81 across the park to Ft. Totten; and finally the D30 down North Capitol street to return to Union Station. We'll have lunch in the station's food court. Bonus: travel bingo cards will be distributed for those who want even more from their transit outing! Hope you all can make it!
