Ship it, complete it, good enough, fake it, get it done, act as if, produce.
It doesn’t have to be perfect. It doesn’t have to match your ideals. It doesn’t have to match anyone else’s ideals.
From one of my favorites, the Cult of Done manifesto, number 13: done is the engine of more.
Crafting, honing, perfecting, and improving all have their place. But getting stuck isn’t a place, so don’t find yourself there.
If the engine won’t start, get out and push. If the job isn’t working out, fight hard for a new one. If the idea won’t finish itself, start over or move on. If the paint sucks, pick a new color. If you’re not running enough, start walking faster.
Don’t be static just because your scared, hesitant, or unwilling to push forward.
Have good reasons for the things you do, or stop doing them.
