Very true. I've also heard GSP talk about how scared he is come fight time. I'll try and dig up the interview. He said the last thing he thinks before entering the cage is, "what the hell are you doing here".
It seems a common thing with fighters. Its something I love as a fan when they are honest about their feelings.
ďIím afraid, like itís the end of the world. Of course, I get nervous. I always have doubts, Iím always afraid, but thatís what makes someone courageous, when he does something when heís afraid. When you do something when youíre not afraid, itís not courage. - GSPĒ
