Moving closer to work. I live in São Paulo, Brazil, and I used to spend an hour or more in traffic every day, just sitting in the car getting frustrated and anxious. It was a waste of my time.

I just finished reading BJ Fogg's new book, Tiny Habits: The Small Changes That Change Everything. Fogg explains that the best way to build a new habit is to start small and succeed, rather than starting too big and giving up. For example, rather than trying to exercise for 30 minutes a day, he recommends aspiring to do just one push-up, and doing it consistently. This approach may be helpful to those of you who want to spend more time studying. If you hold yourself accountable for watching, say, 10 seconds of an educational video every day — and you do so consistently — the habit of studying daily will grow naturally.

I am kneeling because I have to do something. Anything. We all do.

But part of practicing to me is actually an active enjoyment. When people ask, “How much do you practice and do you like practice?” Well, I think it’s always getting your mind to go from “I should” to “I want.” It’s like the magic button that only you can locate. When you’re doing the “should” thing, time happens very slowly. Ugh, I’ve been practicing forever! Fifteen minutes. But when you want to do something, an hour has passed. Your control of time depends on whether you should do something or whether you want to do something.

Professionally, when I lost my first Wimbledon final. I am also disappointed I didn’t learn Spanish when I lived there.

Driving home on my own, thinking about the last 18 months, which have been really difficult, and getting back to playing tennis again without any pain in my hip. It was happy crying.

I am happy to sit in silence with my wife and I think that is a good sign – we are just happy being in each other’s company.
