1) Come up with clever project idea.
2) Decide you don’t have time for it right now.
3) Write down a 2-3 word phrase designed to remind you of the idea. Importantly, do *not* provide enough detail to actually recreate the idea.
4) Fast forward several months; get more free time.
5) Look over notes, re-discover 2-3 word phrase.
6) Fail to remember what made the initial idea clever at all.
7) Curse self and abandon project.
I am on like my 7th iteration of this. :-/
