I think the key. And the reason why people that are older are successful is because they never gave up. You can't give up. People always say, work hard, pursue your dreams and never give up. It's so true. So just because you didn't succeed in your multitude of projects over the course of two 510 years, it doesn't mean you have to give up.
It means that you've learned so much that now in your next project, you should succeed in the way that you want to succeed. So you can't give up. Don't give up. Never give up.
