I have been "struggling" with this myself for a long time. It doesn't affect my day to day life but I'm still searching what to do with my life. So much I want to do and so little time.
I saw some mentionings of philosophers. I would love to read what philosophers said about "regret". Does somebody have a list of books or sources to read about this subject?
This is exactly what is was trying to build for myself. I saw that no tracker was simple and still full of functions. Except for the tax part. I'm still building my own but you gave me allot of great ideas
