I think it's important to have a good hard failure when you're young... I learned a lot from that. Because it makes you kind of aware of what can happen to you. Because of it, I've never had any fear in my whole life when we've been near collapse and so on. I've never been afraid.
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
