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.

Finding gratitude and appreciation is key to resilience. People who take the time to list things they are grateful for are happier and healthier. It turns out that counting your blessings can actually increase your blessings. My New Year's resolution this year is to write down three moments of joy before I go to bed each night. This simple practice has changed my life. Because no matter what happens each day, I go to sleep thinking of something cheerful.

That night, I realized there are no warmups, no practice rounds, no reset buttons. Every day we're writing a few more words of a story. And when you die, it's not like “here lies Drew, he came in 174th place.” So from then on, I stopped trying to make my life perfect, and instead tried to make it interesting. I wanted my story to be an adventure — and that's made all the difference.

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.

Over the years, I have found a few resources for developing personal productivity that I love. My top picks include Getting Things Done by David Allen, the classic The 7 Habits of Highly Effective People by Stephen R. Covey, and Learning How to Learn Barbara Oakley (I recommend the Coursera course). I'm tempted to add Tiny Habits to this list.
