I think they let down when they think they're playing an opponent that's not that strong. They've got to learn that you have to play at a high quality all the time.

I'm not going to let my opponent take something away from me. I want it more than anyone else, and am willing to work hard to become a world champion someday.

I think it's important -- we know we're not as strong, but we can learn from them,

We're not hitting on all cylinders, defensively. When we're playing good, I'll let you know.

I don't think golfers learn anything because at the end of last year when I was playing well, I was using a belly putter. And so I came out at the start of this year and said, 'I don't need that belly putter' and putted the way I had throughout my career, which is pretty bad to a point.

I did not learn everything I need to know in kindergarten
