Stacy is a Maker, a kind of tech-based DIYer and inventor. Creativity is, of course, important for the DIY hacker, but it's essential for everyone else too. Creativity is creative problem solving, and it's something that you can train. If you aren't "working your creativity muscle," your creative skills are going to degrade. Try to push the envelope and find outlets where you can apply your creative skills!
Like a lot of people in the tech world, Joel has a box of Arduino stuff that is gathering dust somewhere. How do you get past that initial "hello world" LED blink project? Stacey recommends to immerse yourself, see what other makers are doing and find inspiration from them. Try to find something that you enjoy and find fun and see if you can do it with an Arduino.
Lastly, Stacey tells us her story of what caused her to begin teaching children technology, and how she got to where she is now. It's rewarding to celebrate people's successes and provide them with a space where they can fail safely. If there isn't a community meetup for something you enjoy in your area you have the complete ability to start one yourself and be the organizer. There are multiple platforms that help organize events. The key for your community to grow is to be consistent with it.
