I started this process recently and I can't tell you how much it has alleviated my anxiety about "losing all my ideas"!
Whenever the idea of choosing just ONE thing came to me either from others or myself, I'd just feel so trapped and torn apart with anxiety over that prospect.
So now I have a huge sketch pad I use for random ideas that come to me, like Davinci's notes, and I have binders for different areas of my life, like home, fashion, health, etc.
It feels so much better!! Like I'm honoring each topic that drives me. There's soooo much knowledge to be had, it's exciting!
