Folks. Compliment your creatives.
It's crazy how far a small compliment can go.
An anonymous person just submitted feedback for my game pointing out a few places for improvement as well as telling me what she liked about my game. That alone fully refilled my motivation bar for the next week or two.
If you want more cool stuff, don't be afraid to tell the creators how cool the stuff they're creating is. You'd be surprised how much it means.
