Me : In what?
X : Business, Life, General?
Me : Failure is a necessity for success. Given it's mostly a system of privilege with a bit of lottery added for goodwill then ... fail often, fail fast.
X : How can I avoid failure?
Me : Be lucky.
Me : it'll stop you doing daft stuff by adding in communication, challenge and learning. But it's no crystal ball. Failure is a necessity for success ... we can't all succeed.
X : So what's your advice?
Me : Either embrace failure or pursue another goal.
Me : Try contentment. It's not possible to create a world where everyone succeeds. It is possible to create a world where everyone is content (or at least close to being content).
