Oh, I'd love
to be a 'fool' like Federer - four Grand Slams, two Masters Cups, world #1, a million dollar salary, you know... Very foolish by my standards, eh?
And do you think Sampras or other Wimbledon (and Grand Slam in general) greats didn't lose the occasional set/s while playing? I'm pretty sure they did, actually. And Sampras still won seven Wimbledons, but I guess he's foolish, too.
