I think failure is nothing more than life's way of nudging you that you are off course. My attitude to failure is not attached to outcome but in not trying. It is liberating. Most people attach failure to something not working out or how people perceive you. This way it is about answering to yourself.
I've had to be a man since I was 12 or 13. I had a job. And I was playing the piano for people twice my age. Handling responsibility is what makes a man a man.
