I remember staying inside post-highschool era (interregnum) playing PC games day in, day out for around 5 years. It was 24/7 pretty much, with the occasional exception of eating, shitting, and sleeping. Also drinking. Didn't really care for much of anything else. That really bit me in the ass later in life because I missed out on real life things. For example, a girl from the very same highschool wanted to date me afterwards. Bbbbut I didn't care about that either, never really did. And they'd sooner than later find out I'm not somebody they'd like anyway so what does it matter.
And even in highschool I would simply come back and just play PC games. It's all I would do, it's all I ever wanted to do since I assumed my limitations in this world after calculating myself in imaginary situations. Not to say I couldn't do anything else but rather, I know playing PC games is probably one of the only things I'm good at. And I continue to play them to this day.
I would do other things, like something productive, and advance myself but quite frankly it's just too damn tedious to get into.
