Absurd, huh? Not really. It's the same thing.
People walk because their parents absolutely, positively would not give up teaching them to walk. It's that simple. We need more of that thinking when it comes to "raising our businesses".
When I hear about people starting businesses and failing, I wonder if it's because (a) the business never had a chance or (b) they gave up too soon. I suspect it's a lot more (b) they most people would admit.
I think the secret to not giving up is finding a cause that's just about as important as teaching your child how to walk. This depends upon how your hard work will benefit others, not on how cool it is, how much fun it would be, or how much money it will make. You will have to succeed because of those who are depending on you just like your child depends upon you to teach them to walk.
