I was thinking to coach kids and maybe do clinics, but I didn't want to step on a tennis court anymore. I decided to do something completely weird. I lived on a little bay in Sydney and my brother Ben was there too. He invited me to come clean boats with him. I was thinking, 'Sweet, I don't have to teach anyone to hit a forehand and I can just clean boats and relax.'That's what I did for the morning and afternoon and I'd ride my bike down to the bay. It was incredibly frustrating, because I was 23 at the time and life was going so quickly. I felt like I hadn't gotten anything from the game yet and hadn't reached my potential. But I always had in the back of my mind that I was going to get back out there once I was healthy and ready. When I decided to come back in 2019, I had a breakthrough year."
