I've never set out to be a spokesperson for women's equality. My experience of working with Amelie Mauresmo gave me a small insight into attitudes to women in sport and, because it was unusual for a male tennis player to work with a female coach, I am often asked about that. Working with Amelie was, for me, because she was the right person for the job, and not a question of her sex at all. However, it became clear to me that she wasn't always treated the same as men in similar jobs, and so I felt I had to speak out about that.

Sleeping by 9 pm & getting a workout at 5 am has been helpful. Sleeping early reduces the chances of bingeing when we are drained and have low self-control at the end of the day. A workout in the morning also increases the odds of making healthier choices throughout the day.

Even I can't predict what kind of car we will be driving 20 years from now, but my time at Babson taught me to embrace change rather than run from it, and I urge all of you to do the same.

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.

The second filter is to gravitate towards working on hard things. I’d love to tell you I was an immediate success after leaving Stanford… I wasn’t. Even a decade later, I felt like I wasn’t on the right path, and it took me a while to find my footing. Until I applied to Google. I had my final interview there in 2004, it was April Fool’s Day and the day Gmail launched. So when my interviewers asked me about it, I wasn’t sure if it was a joke or a real product. That’s because at the time, one gigabyte of free storage for everyone felt super ambitious, and almost impossible. A couple years into the job, I got my chance to work on a seemingly impossible problem, too. It was around this time that the internet was moving into a new phase. The web was evolving from simple web pages to rich applications. There was a group of us that felt we could reimagine the browser to be much better and faster, and we had an early prototype that we thought was pretty good. Internally there was a consensus that building a browser would be incredibly difficult, requiring hundreds of engineers; we had a group of about ten. The consensus was right. It was going to be really hard. In some ways we were naive, and it's good to be a bit irrational when you approach new things. And in 2008, we launched what we thought was a great browser. We had eight million users in the first twenty-four hours, and the reviews were really positive. And then user growth stagnated. After a year, we had around two percent share. I remember Steve Ballmer, the CEO of Microsoft, made fun of Chrome in an interview and called it a rounding error. It could have been demoralizing. But with that California optimism, I told the team that the fact he went out of his way to dismiss us meant we were doing something right. We kept going, setting highly aggressive stretch goals to keep the team pushing. We rapidly iterated, shipping the browser every six weeks while others shipped one maybe every six months to a year. Success began to follow. Working on hard things has taught me a lot: It typically attracts other great and optimistic people. And even if you miss meeting the high goals you set, you’ll still achieve something great. So when you have the choice to work on something hard — say yes. Do what excites you

So take the time to find the thing that excites you more than anything else in the world. Not the thing your parents want you to do. Or the thing that all your friends are doing. Or that society expects of you.
