Do what you are best at and let others take care of the rest.

Something worth doing might take a while, so really flesh out the potential of the business and be honest about whether it's worth doing. If it's not a $100 million company in five years, maybe it'll take 10 or 15 years. If you're doing something that has a universal, timeless need, then you need to think of the company in a timeless way.

You need a team that's going to care about this thing as much as you do.
