sometimes i find myself doing more frequent breaks or playing a video game (that tends to be 2 or 3 games), when i have a hard task to solve that I know is a headache.

but i've been trying to force myself to bruteforce it regardless. i think thats a muscle. you need to train your muscle to head on towards hard tasks and get them done rather than being stuck on them for a few days.
if i dont do this, i slack off on anything that is harder than usual. and most things i do these days are not simple, they are quite hard compared to what i was doing say a year ago. example a trade on a tail venue with a weird api that doesnt match anything i have built for other other venues. i can either procrastinate on that for a week, or just get it done.
i view my work increasingly as a pain in the ass. but thats where you get paid more for. to solve those issues. your competition is struggling the same as you. probably more as they have other mandates that aint as flexible as yours.
just get it done man. the frustration that spawns off your procrastination aint worth it. you have to get it done anyways so why delay that.
