Even if it means slimming things down from your ideal version 10 to version 1.0 or 0.01. Finishing things is a real skill that we want our name to associate with. It protects our limited time, energy, and resources. Half done / almost isn't it. Would you rather work with someone who gets it halfway done or someone who finishes what they set out to do every time? It's better to work with a hard-ass that finishes things than the fun person who doesn't. 

Protect your time work with the finisher. 

Even in the situation where you don't care and you just want to have fun...do both but most importantly finish.

Protect yourself, be a finisher.
