I've always been pretty careful at keeping track of my spending, so using my debit card is often the easiest way of doing that.

I'm incredibly fortunate and it's important to me to make sure that I give back where I can.

Where resources are plentiful (i.e. no constraints), you will find very little creativity. Where resources are scarce (i.e. many constraints), you will find an abundance of creativity.

I've always been lucky enough to just play tennis, so I never actually had a job when I was growing up.

I try to anticipate the ball well. That's something that's helped me since when I was a kid. Just learning to anticipate and read the game well. That's helped me. When I moved over to Spain and I was 15 I was playing with big guys who were 22 years to 28 years old and I was 15 so I couldn't beat them with power. I had to beat them with touch shots and variety and anticipation and all of those things. I learned a lot when I was over there.

In tennis, it is not the opponent you fear, it is the failure itself, knowing how near you were but just out of reach.
