I made a commitment to take ownership of my life. I started to get more connected, and then I just kept going with tangible daily goals. It wasn’t about a destination. Getting back to number one was something I was pretty convinced I’d never achieve. But that journey from rock bottom to the summit a second time was a great accomplishment for me. Without it I don’t know if I would believe in myself as much as I do when I face other challenges now. ... regardless of what the score is, the most important point is that next point. ... A great rival is like a mirror. You have to look at yourself, acknowledge where you fall short, make adjustments, and nurture the areas where you overachieve. There were times my rivals brought out the best in me; there were times they brought out the worst. They probably helped me win things I never would have otherwise; they also cost me titles. I don’t know how you quantify what it would have been like without a rival like Pete Sampras. I would have won more. But I think I would have been worse without him.
