I love going to the tip. A friend reassured me once that if I ever get cancelled, I’ll still have the tip, and she was absolutely right. Even Britney Spears has the tip! It’s never going anywhere, and that’s a nice thought.

I call it “stolen time”—there’s nothing more valuable than stolen time. It happens to me sometimes when I’ve set up a meeting at my studio at a certain time and it gets cancelled on short notice. When it happens, I’m like a giddy child. I think, “Wow, I’ve stolen half an hour. It’s so exciting—I can do whatever I want!”

All my life, I've gone through life anticipating trouble. And here I am, well along on my eighty-fourth year, and like Epictetus, I've had a favored life. It didn't make me unhappy to anticipate trouble all the time and be ready to perform adequately if trouble came. It didn't hurt me at all. In fact, it helped me.

I then converted a bathroom, seldom used by the family, into a laboratory and spent hours playing with chemistry sets. With the help of an aunt, Esther Molina, who was a chemist, I continued with more challenging experiments along the lines of those carried out by freshman chemistry students in college.

Like you can do anything.

Taking time every day to read the Bible.

Any lost match is, of course, disappointing, but every loss is a lesson to be learned.

I never wanted to have to choose between tennis and a family. I don't think it's fair. If I were a guy, I wouldn't be writing this because I'd be out there playing and winning while my wife was doing the physical labor of expanding our family.

But these days, if I have to choose between building my tennis résumé and building my family, I choose the latter.
