任何項目的運動員，都一定不能永遠保持最佳狀態：有時會如有神助，有時卻力不從心。誰人都能在狀態好時發揮得好，然而真正的冠軍，卻能在不妙的情況下，也能堅持自信；在種種失意之下，也不沮喪。

瑞典網球手 Stefan Edberg 是位出色的運動員。他是甚少在單打和雙打中，都曾是世界排名第一的人。他認為，若要常常取勝，最重要的心態，就是在逆境中也能冷靜清醒，堅信自己一定會闖過難關：

"The most important thing [in tennis] is to have belief that you still can win even if you're down. Winning from coming back once, believe you can do it twice, believe you can do it again, and again, and again, which is very important. Everybody can play when they're playing well, because it's running for you, it's easy. But when things are going against you, then the mental aspects come in. Can I still win? Do I believe I can come back? Yes I do. I never give up, because I know there is a chance that I can come back. And when you're out there and everything is going wrong, you've really got to start thinking. What can I do? What have I done? What's gone wrong up to now? What can I do to change the situation? During the game you've got to be thinking. In tennis you have ten, fifteen, twenty seconds between points and one minute in the change-over and you've got time to think, and that's what I think is the wonderful thing about tennis, there's no coaching allowed. You've got to do it all yourself. Nobody can help you. You're just out there by yourself and you're going to have to think and change things yourself. It's a lot easier if someone else tells you, who is watching, but from my experience, most of the time I know what to do. Sometimes you can't do it because it's not your day. You can't change your game too much but obviously I try to do different things."
