At least nighttime you just wants to play video games. When I was a young man, nighttime me wanted to go out dancing, get shit faced, get into fistfights, and paint the town red. That's a lot harder to recover from at work the next day than a late night video game session.
Well, nighttime me was an asshole of the highest rank. Daytime me just wanted to build a better life for myself. Nighttime me was trying to cope with the ridiculous difficulty and stress of that aspiration.
