Here is one that was passed down to me, and it is a lesson I have had to learn the hard way. Most startups fail because they give up. It isn’t the best idea, the most-talented team, or the one with the most money that necessarily succeeds. It is the startups that don’t give up that eventually make it. The journey probably won’t be as pretty as you want — and success may look different as well — but if you passionately believe in what you are doing, you can find a way to keep your dream alive.
