You're the best in the world, so you deserve those little perks along the way if you can get them.

I started mountain-bike riding two years ago, which is much better than riding a stationary bike in the gym. Mountain biking is a total body workout.

Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself. Taking time out with family and friends helps to maintain the work-life balance everyone needs.

Daniel, my big brother, is eight years older. I'm lucky he didn't mind hanging out with his little sister and my younger brother.
