What do people think of Habitica?
I've been using Habitica (previously Habit RPG) for years now. If you haven't tried it, you should. It's a fun and easy way to turn your life into a game and feel like you're winning at it. :D
Pro tip (from personal experience): If you find yourself with a lengthy task list that you never finish and just feel guilty about, scrap it and start over with smaller, actionable items. Life should be fun!
