I wasn't highly touted coming out of high school, so it wasn't like I was expecting to get a lot of minutes. For me, I didn't know how good a player I was, even though I think I did decent as a freshman.

When I was growing up, there wasn't too much technology. There weren't so many channels that we were glued to on TV. We had to go outside and create our games. Kids had the habit of being active and exercising, just enjoying the fresh air.

It's similar to basketball: when you go to different gyms and win or lose, you learn something new. So when kids get out of the classroom, go to a new environment and meet different people, it opens their eyes to new things, and they have fun learning.

The biggest thing is to give it back. You want to leave the game in a better situation than you came in with it. That's really important to me, especially being an avid reader and just learning about how to build businesses, learning how to make the most of the business you're in, the ins and outs of the relationships that you build as well.

These days, you can watch many different sports; you are saturated with it 24 hours a day. And young boys all want to be footballers because you don't even need to be that good, and you can still earn £100,000 a week."

I know sport can change the world, and that matters to me.

I'm always bragging, always laughing with my Spain team-mates at Barcelona, saying I'll take 30 per cent possession and two goals - a win is a win. It's football.

In professional sports, things can change quickly. You keep your balance. You keep your perspective, and things will work out.
