What do you guys fill your time with?

so I'm mostly home alone now with my two cats (gf dorms at school and comes every other weekend). I fill my time mostly with Netflix or other streaming service or doom scrolling on social media (reddit included). I have some hobbies that are mostly summer/spring hobbies and even if I start going to the gym it'll only fill 2 hour of my day max.

I suppose this is more for people without kids because kids take up such a big part of life, so what do you guys do to fill the time from when you get back from work and go to sleep. with noone home to engage with.
