I don't take long-term notes at all, only quick notes on paper of thing I need to do. I tried to collect all thoughts, notes etc. but I would never read them again. Most of it would be outdated anyways. So I understand that these kind of notes might feel like ballast and might be a reason to not be able to close with things.

Everything that is worth keeping is on my website as properliy written posts which I enjoy to re-read from time to time. You could also look at it this way: anything that doesn't make it onto the website - i.e. is published - isn't worth saving either.
