finding motivation is really hard. though i will say (as much as i DO hate to say it) get rid of the ability to doom scroll, get rid of insta, tik-tok, youtube etc. its going to SUCK but then you're going to get bored and you will have to do something (boredom breeds creativity). the best type of motivation is sometimes just discipline, depending on what you're doing but besides that try to experience things more. go out for walks, get friends together. the more you live your life, the more inspiration and motivation you will find. work on projects with friends, find people online to talk about passions with yk that type of stuff.
also just remember that finding motivation isn't easy for most people, and its never ALWAYS easy for anyone. sometimes you have to push yourself and then the motivation will come later, sometimes you won't be motivated and that's okay. the best thing to do is do something, everyday if you can, even if it's small. work up to big things, journal, keep track of how you're getting better at putting down the phone and getting to work, on whatever it is. be proud of yourself. yk?
this advice isn't perfect but it's something :o)
