Excellence prospers in the absence of excuses.
Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself.

I have spent a good many years since--too many, I think--being ashamed about what I write. I think I was forty before I realized that almost every writer of fiction or poetry who has ever published a line has been accused by someone of wasting his or her God-given talent. If you write (or paint or dance or sculpt or sing, I suppose), someone will try to make you feel lousy about it, that's all.
My biography of Frank Sinatra is not paean to his music but rather an illumination of the man behind the music, who once described himself as 'an 18-karat manic-depressive who lived a life of violent emotional contradictions with an over-acute capacity for sadness as well as happiness.'
