Some days you might be excited to game, while other days you would rather want do something else. Do you listen to your mood, or stick to a regular gaming routine?
It's both for me, I prefer to stick to a schedule especially on weekdays but it also depends on my mood if I want to play a game too. Some days I might want to focus more on other things and less on gaming, other days I might want to play a game to escape from the real world for a moment.
I don't have a schedule, I play based on mood. If I have time and if I do not have pending deadlines, and if I am in mood to play games, I spend time playing games. I do not have a fixed gaming schedule.
I usually listen to my mood. If I genuinely feel like gaming, I'll play. If I'd rather read, go for a walk, or do something else, I don't force it. I try to keep gaming as a choice instead of a routine.
