Earlier quoted context omitted.
Working your butt off has zero to do with having a executable vision that creates value. Clearly shit needs to get done, but there's only so many hours in the a life of a startup and being able to see what needs to be done ultimately is more important than just getting stuff done. __ "I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it." - Bill Gates
Oh, I agree that a startup needs an executable vision. However if someone provides just the vision but doesn't put as much work in as everybody else that's an advisory role, not a co-founder role, and should be reflected in the equity distribution. The thing is that vision is just so much easier than actually doing the grinding grunt work. "Vision without execution is hallucination" - Thomas Edison
I like this one better:
If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them. -- Henry David Thoreau
Both quotes are getting at pretty much the same point, I think, but the Thoreau quote is kinder, and more encouraging.
