I just started using obsidian. It's perfect for starting new projects because even when you don't finish, you don't have to completely restart.

Good notes are great, but only if you can find them. For half a year, my notes were just the date. It became an issue when I needed to remember a project I worked on in March but didn't finish. Having links and screenshots and visually seeing relations between ideas has made it much easier to pause and come back later.
