If you let that feeling in for a bit, can you figure out why you feel like you're wasting your time? Is it inefficiency or just plain waste?
I felt this way about Diablo 3 for a bit, at some point I thought "I could've learned 3 languages by now instead of this". Turns out I still like gaming, but yeah, I really do also want to do other things with my time. So no more grindy stuff, I'll game, but more the stuff I can play for 30 minutes and stop, or alternatively some RPG/single player game that I can play for 40 hours over a few weeks to get my fill, and then move on.
