How Do I Become a Better Loser?

Whenever I watch snooker, and the match is over, the losing player always extends his hand to the winner. In post match interviews, they almost always have great things to say about their opponent. While I don't throw tantrums, I can definitely be a sore loser at times. I am very competitive and hate losing, so when I do lose, I feel like it's always because I didn't play to my standard.

Maybe it's deeper than that, but I'm no psychologist.

Anyone have any suggestions on how I can improve in this area?
