When you start creating something, anything, there is this feeling. Every time you make something, you will get that tunnel vision. It's that itch you just have to scratch. God knows what'll happen if you don't. For me, that's something I've come to accept. But the problem is, for some people, they can't stop feeding that urge. They have to find new things to make. Salvage the old, and stir it into the new. Don't keep your hands idle. Right? It's their workshop after all.
