"I had a vocal lesson today, and I will have one tomorrow, um every single day, five days a week, every week. I study. Maybe five or six years ago now, I really realized between 25 and 50 I was bulletproof, I could do it to get away with.
From 50 in order to be even better, I had to work harder, and so I take it very very seriously that I don't want to go on stage and hurt my legacy.
I want to be better."
I'm pretty sure he was talking about his tennis lessons >_< jaja
