I can literally play games from the time I wake up until I go to sleep. However, it does make me feel guilty to do that, like I haven't accomplished anything in that day. Usually lowers my self esteem and makes me suck at videogames, so it's a win/win for me to not do that.

For example, if that was confusing:

I can play videogames for 16 hours straight and feel guilty/start to think about it while I'm gaming, which messes up my gaming (usually am playing online multiplayer games).

or

I can not play for that long, and be really good at the game because I don't feel so guilty about playing it.

It affects my performance.
