From 13 years old, I was treated like a professional.

My career has been very difficult. People respect the fact that I haven't just turned professional like Amir Khan or Audley Harrison, and it's been, 'Here's a million pound' - for spoilt brats to fight a couple of fights.

My first boxing memory is watching Marvin Hagler and Sugar Ray Leonard on television.

I find it quite sad to see the likes of Evander Holyfield carrying on past their sell-by date.

You get these horrifying straight-to-video things for very little money, then you go to the Cannes Film Festival, and they got some poster of you, 40 ft. high, in the worst movie in the world.

We used to tie-dye T-shirts and sell them to classmates. We used to make egg rolls and sell them at street fairs. I worked at the mall. My parents probably spent more money on the gas driving me to different jobs than I made.

Most of the money I make now comes from investments from CrunchFund. And the vast majority of that is what's called carried interest.

I'm focused on the next generation, because I think it's very hard to break the habit of adults who've got salt and sugar addictions and just ways of being in this world. It's very hard even for the most enlightened people at famous universities that are very wealthy to spend the money that it takes to feed the students something delicious.
