From where I stand, it looks like you have your numbers backward. The reason you start a startup is so that you can work those 15-20 hour weeks (or less) without anybody giving you grief about it.

You can do that and still have plenty of time for product development working 10 hours a week.
You can make up quaint terms for it, but really all that does is flag it in your mind as something that's not for you. You really need to be doing that 80 hour week boiler room thing, else you're not startupping enough. So you do, and you're unhappy.
