@The Prompt Challenge

Great way to improve you prompting skills through daily exercises. This should be implemented in schools, would really help students. Can also see it being really valuable for adults. Not just for prompting, but for articulation in general. Also made a video about it: https://www.youtube.com/watch?v=A8ZRJgLCFy8

The idea is cool, doesn't really live up to expectations though.

tried it and skimmed a bunch of entries on dreams, animals and numbers. The write-ups tie symbols to headspace in a way that actually gets you thinking, a little horoscope-y at times but I still pulled a few solid lines for my journal
