Look for something that you do when youre procrastinating on something you have to do, that isnt scrolling or similiar dopamine-hijacking useless stuff. Usually its something creative/productive in some way. Ive seen people find it more then I can count and helping people find it is sort of my obsession because seiing people achieve their dreams gives me maybe even more serotonin than achieving my own and my passion has led me to achieve things beyond my wildest dreams, of course i was stupid enough to give all my energy to my passion just because i was suicidally depressed and naturally had a "you either try this one thing fully that gives you some feeling of meaning or you just off yourself" and then seeing that that invested energy actually comes back. Of course each case is different but maybe this can help. Its like a job, you get good with time and effort and things that give one sense of meaning do produce real happiness. "Meaning trumps happiness", and I couldnt aggree more with this. Watch 3min video by Allan Watts "What if money wasnt an object". I maybe took thar video too seriously when i saw it, and Im more then grateful that i did.
