Build habits, one a month. Figure out the sort of person you want to be, the life you want to live, and determine the habits that person would need to live that life. Then make that person real by motivating yourself one habit at a time.

Really good advice. I'm someone who has gotten mostly out of my bad despression and can motivate myself to do things to a limited extent (I can clean for like2 hours before I quit and need to build up the energy), but building the good habits is exactly what helped. Making it eventually feel weird not to do something. I feel shitty if I don't workout, run or walk for a couple days because it feels abnormal. I clean my bed every saturday because I am now addicted to the clean bed feeling on saturday nights. it's har work to get there, and I still need to be better in many ways (sitting to read more instead of scrolling through news and hexbear, clean more than just the necessities before it becomes visibly bad) but it's helped me a lot
