1. you choose a fixed duration of time within which to journal (i choose 15 minutes even though it is initially tough to spend all of)
2. if you stop typing for more than a few seconds within the duration, you lose your writing
These constraints basically force me to dump anything and everything on my mind for the sake of continuous typing (to not lose what i've written), and I've been successfully doing it at least 1-2 times a week for a few years now. All your entries are also saved locally in-browser only, with the option to export a savefile. Source code: https://github.com/krrishd/write

For TODO list / task management stuff, I'm actually in the middle of building my own command line task manager tool that maps specifically to the way I like to do things. Once it's a little bit further along, I'll release it as Open Source in case anybody else might find it useful.
It stuck because it's just markdown, vscode is always open and it syncs to plaintext in dropbox so is greppable, accessible from basically everything.
