I'm a weird person so no judging pls but i created this reward system where I get like 20 cents for shower or a dollar for exercise and the money i "earn" this way is the only money i can spend on pleasures. No clothes, no books, no fun stuff unless I get my shit together and do what I gotta do. I only buy necessities otherwise. It sounds fucked up i think but idk works for me pretty well (not perfectly though).
