“Perseverance

I’m convinced that about half of what separates the successful entrepreneurs from the non-successful ones is pure perseverance.… Unless you have a lot
of passion about this, you’re not going to survive. You’re going to give it up. So you’ve got to have an idea, or a problem or a wrong that you want to right
that you’re passionate about; otherwise, you’re not going to have the perseverance to stick it through.
