I was a huge Mike Tyson fan growing up; his fights were always on in my house.

I struggled with being a broke college graduate, and while all my friends were getting career jobs, I was working horrible part-time jobs. That's why now, even when I get tired, I think, 'This is what I asked for.'

When I was in college my girl got me a job at the doctor's office she was working at. I was a file clerk. No disrespect but I don't think a man can do that job. It takes so much meticulous and precise file-keeping.

I'm the same kid who used to hop the trains with headphones and just go to downtown Manhattan, walk around and listen to music or walk through the city. The fame restricts that. It's a small complaint in comparison to the benefits I get from it, but the restrictive part is what I don't like - and the fact that it's not reversible.

The success or failing in one competition doesn't define you, and that is one thing that any sports would teach you.

It is true that the aristocracies seem to have abused their monopoly of legal knowledge; and at all events their exclusive possession of the law was a formidable impediment to the success of those popular movements which began to be universal in the western world.

YouTube began as a failed video-dating site. Twitter was a failed music service. In each case, the founders continued to try new concepts when their big ideas failed. They often worked around the clock to try to overcome their failure before all their capital was spent. Speed to fail gives a startup more runway to pivot and ultimately succeed.

I realise now that a lot of the things I was doing weren't helping me to get to the goal I want to achieve - to become the champion of the world.
