A lot of times, in the beginning of my career, I put pressure on myself just because I wanted to perform so well. I just wanted to be perfect.

I want to beat the best out there and whoever is considered the top fighters of my era.

If you're the best then take the test!

My skills are still my skills.

Me and my team always work so hard outside that square circle.

I fight myself. I don't fight to break Ali's record or Sugar Ray Robinson's record. I fight to please myself. I know in my heart where I'm rated. I didn't fight in Ali's era. This is my era.

You know, as a young child, I lay in my bedroom and I swore to myself then: 'I'm not going to smoke and I'm not going to drink.' And I said I'm not going to just say that when I'm a kid. I'm going to stick to that as an adult. I kept that in mind my whole life.
