I have to stop working on it for a while when I get stuck.

I feel you there bro. Sometimes, when I'm creating a piece of music, I get to a point where, I'm just not making any progress, I'll step of for a piece, let it simmer for a bit. Same with servers in general for me. It's the reason I have a test server and have, in the past, leaned a bit heavily on a few backups. LOL! I can screw something up quick when I'm frustrated. The reward for me is learning something new. It's a rewarding and useful hobby for me. among others.
