Another thing I took for a friend is to number my folders.
For example, I would have
00_perso
01_projects
00_projecta
00_projectb
Somehow my brain is better at remembering the numbers than searching for a folder name.
Using that for a few weeks, I realized that I actually started to organize stuff ore, because it was easy to find them.
Ex : gitconfig would be 00 01 .gitconfig
My billing 01 02 02
etc. . .
Starting using that technique ended up making myself organized.
