When polo is used as a platform to give back, then it becomes much more beautiful, I think.

In the beggining of I was getting all this feedback from people saying, "What are you doing? What is this?" But I thought to myself, "This is a great opportunity. This is a perfect bridge to help me achieve my dream and my vision of polo becoming a bigger, more visible sport." So I used the money that I was getting from modeling to buy better horses and to become a better player. So I really believed that if I could elevate my game and show that I was serious about it, then the work I was doing with Ralph Lauren would become that bridge that I was looking for to take the sport further.

One out of four kids in Lesotho has AIDS, and the idea of the charity is to help the children first fight the stigma of living with HIV and then teach them how to live with it and survive and get an education so all these children can have a normal life. When you're changing the life of so many kids - one out of four is a big number - you change the direction of an entire nation.

Charity is another passion of mine and I think it's important to give back. I'm a lucky guy, I've had a great life, I have a great family. I'm very blessed that way, so I believe in giving back a lot.

A friend of mine had this idea a few years ago. We thought it would be a great way to promote the sport and to put polo in front of a lot more people in an unexpected place: the romance novel. There's a lot of people that care about those kinds of stories, especially women, and it would help people to know what the polo life is all about. It's not just what you see in the newspapers or on Pretty Woman. There's a lot more to it: the time spent in the barn, how much we love the horses, the relationship with the horses and with the family, etc.

I have to say my relationship with the horses is the biggest thing, and it grows. I love horses more and more every day, and I'm breeding, so when I'm playing a horse that's the son of a horse, the daughter of a horse I used to play, it's like bonding. So I think that's the most amazing part of it. It's the passion that we polo players have for the horses first, and then the game and the strategy of the game and winning and the team and your teammates, all of those things are a big part of it, but the horses are my favorite part.

I started playing polo when I was nine years old. I'm from Argentina, so in Argentina polo is more of a common thing. We have a lot of horses and a polo tradition and it's something that goes from generation to generation.
