Dave Grohl

I can understand how some people might resent me for having the audacity to continue playing music, but it'd take a lot more than that to stop me from doing it. I started Foo Fighters because I didn't want to retreat.

It's not just the physical aspect of boxing, it's the whole fighter mentality that has been ingrained in me through the years as a competitive athlete. One of the hardest things you'll ever do is to box - to get into the ring and to face off with somebody whose whole goal is to knock you out, to hurt you, and to be able to fight back.

Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.
