To be a top-class athlete, you have to train hard, you have to eat right, you have to get enough rest. I feel the way golf is going nowadays, you have to treat yourself as an athlete.

With success comes expectation, and I know the expectation on me is going to be pretty high.

I realise that every time my face is on TV or I'm playing in a tournament, that I am a role model for a lot of people and a lot of kids do look up to me. I try to do my best in that regard and put myself across as honestly and as modestly as possible, as well.

Leaving golf aside for the moment, I'd choose Roger Federer as a sporting role model, Muhammad Ali for a sporting and non-sporting role model and Nelson Mandela as a true and lasting inspiration.

I believe that anybody with Mandela's capacity to endure hardship and then forgive is a born leader and example to us all.

In a serious sense, wanting to change something from the past doesn't work for me - change something you don't enjoy now rather than regretting it later.

Everything is firing on all cylinders for me.
