[observation on his career, 2015] To use a tennis metaphor, after a certain point you can't keep charging the net, and you fall back to the lob game. But you can still win.I think I care just as much as I did at the beginning, and I think - at lots of levels - I'm better at it now. You learn to trust signs that something isn't going to work earlier than you used to, or that this person is talking nonsense earlier than you used to, and you're confident enough to to say, "We've got it. Let's move on".
