We'll meet at The Capital One Café, 167 Easton Town Center, Space A-103. This is in the main mall where the Microsoft store used to be, on your left if you're standing at the bottom of the AMC Theater escalator. Join us on Sunday for an hour of uninterrupted wordmaking! • What we'll do Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at noon on Sundays. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: 12:00 - quick intros. 12:10 - timer starts: write for 1 hour. 1:10 - chat / take off / keep writing. OPTIONAL SOCIALIZING happens at 1-1:30ish. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you! • What to bring Whatever you need to be able to write! Bring earbuds/earplugs if you want to block noise or the occasional conversation by other patrons. Electrical outlets are limited, so charge your devices before whenever possible.

Greetings writers! Come down and join your fellow wordsmiths for one hour of uninterrupted writing time in the upper level of the Market District Supermarket in Upper Arlington. The main entrance of the shopping center opens onto stairs/elevator leading up to the 2nd floor cafe section where we will have a table displaying a sign with the Shut Up & Write logo. Writing is largely a solitary craft. Practicing with others in a community setting may be the thing you need to fire your own routine. We’ll meet on Wednesday evenings, starting the clock at 6:30, following a brief period of introductions. This is solid writing time and all inclusive. Any project is acceptable, be it fiction, non -fiction, work or homework assignment. All is welcome and will remain private to you. The market boasts a Starbucks, a full service bar and various affordable food options. Parking is plentiful, free Wifi is provided as well as outlets for charging your devices, though they are somewhat limited, so plan accordingly. Show up as early as you like, or stay late. This group tends to socialize some, both before and after the alloted time, but this is not mandatory to you. Feel free to come and go as you please and late arrivals are welcome. The cafe may be noisy on occasion so headphones/ earbuds are reccommended as you see fit. Please try to RSVP if possible so that we may grab enough seats for all—the venue can be busy at times. Feel free to message me privately wth any questions and/ or concerns you may have. Happy writing!

Join members of the local UX and Digital Design community for a casual monthly breakfast. There _might_ be a little snow, but there _will_ be effectively infinite serve-yourself coffee, so it evens out if you ask me. Just a reminder, while the other locations are great too, we’re at the Lane Ave one this time.

Confidence can be cultivated in many ways—through reflection, conversation, creativity, and practice. In this Confidence Lab session, we’ll explore one powerful pathway: **building confidence from the inside out through physical expression and movement**. This experience is designed to help you reconnect with your body as a source of insight, self-trust, and presence. We’ll begin by grounding into what’s bringing you here, creating space to notice how your body is showing up and what it’s holding. From there, you’ll be guided through accessible movement exercises that invite awareness and choice—isolating different parts of the body, experimenting with movement, and practicing what it feels like to take up space intentionally. Next, you’ll participate in a small-group dance lesson led in a supportive, low-pressure environment. No dance experience is needed. The focus is not on performance or perfection, but on expression, curiosity, and allowing yourself to move with confidence as you are. We’ll close with a reflective group discussion, exploring what emerged during the experience and how these insights can be applied beyond the studio—how you inhabit your body, how you carry yourself, and how you show up in everyday life. **What to know:** * Wear comfortable clothes and shoes that you feel good moving in * No dance experience required * Light snacks and beverages will be provided This session is for anyone interested in deepening their relationship with confidence by listening to their body, expanding their capacity for self-expression, and practicing self-love as an embodied experience. **Featured Speaker: Mary Grace** Mary Grace, the dynamic force behind MG Choreography & Boutique, has been transforming special occasions with her unique blend of artistry and passion for over seven years. As a proud Latina, with Venezuelan and Mexican heritage, Mary brings a rich cultural perspective to every choreography she creates. Her dedication to dance is matched only by her commitment to empowering others through the joy and elegance of movement. Mary’s journey began with a simple passion for dancing, which quickly grew into a thriving business. She specializes in crafting personalized choreography for weddings, quinceañeras, and sweet sixteens, ensuring each event is unforgettable. Determined to make a significant impact in Ohio, Mary established the first-of-its-kind brick-and-mortar location that not only offers a space to practice these beautiful dances but also provides a boutique experience for purchasing or renting exquisite dresses and tuxedos for these special moments. Mary Grace is more than just a business owner; she is a trailblazer for Latina women in the community, dedicated to bringing elegance, joy, and a touch of her vibrant heritage to every event she touches. **What is Confidence Lab?** Confidence Lab is a monthly community experience for bold, thoughtful leaders building confidence from the inside out. Whether you’re launching a business, leading a team, navigating change, or simply striving to show up more fully—you belong here. Our work demands clarity, courage, and conviction—but the pace of daily life can erode our sense of self. Confidence Lab creates space to reflect, reconnect, and grow with others doing purpose-driven work. It’s designed for entrepreneurs, nonprofit leaders, creatives, corporate professionals, activists, and anyone ready to lead with authenticity and impact. ***Please note:*** *All are welcome!
