I don't know about you, but I'm an absolute sucker for productivity systems. Cards, pomodoro, todo lists -- I've tried 'em all, and stuck with a few. But the only thing I've found that actually encourages me to get shit done and doesn't encourage me to waste time organising lists and making plans is keeping a done list.
What's a done list? Think of it as an anti-TODO list: your DONE list is where you write down everything that you've, well, done. You know that little dopamine kick you get from filing a neatly-tagged TODO or marking off something that you've finished? A done list is just that, and the only way to use it is to train yourself to stop organising and just get stuff done.
Try keeping your own done list for a week, and you'll be amazed at how you can hack your brain into actively looking for projects you can finish and tasks you can check off, just so you can write down one more thing as DONE. You don't need fancy tools to write down a list, but if you're like me and you like having fancy tools check out https://donel.ist -- the fast, easy-to-use done list tracker I built for myself. It's 100% free (no ads, "pro" tiers, or feature unlocks). And if you want to automate your done list or use it to automate other things, there's an easy-to-use REST API too.
