I did it my way, and I have no regrets when I look back on my career that it was just a big focus for me.
I've always led a pretty simple life, with few extravagances. The money in tennis never drove me.
I think the image of golfers is terrific, and rightly so.
I'm maybe not quite as sharp as I used to be.
In tennis, you can make a couple of mistakes and still win. Not in golf.
I made it look so easy on court all those years. No one realized how hard I had to work. No one realized how much I had to put into it. They underestimated my intensity.
