I've noticed this on several people, myself included.

You get your rockets, or cowboys and you get more nervous than excited.

I lost a good deal online last night when my KK got busted by an A5o. He caught his ace and paid no attention to my raising. My thoughts after the hand was over, "I need to raise more pre-flop." Different rooms have different people. You will get UTG calling a 5xBB with J3 in 1 room, where you will get Button folding a 2XBB with QTo in another room.

However, if you play strong, you will win the pot. If you just win the blinds, think of it as a success. It is successful. You've just won. Raise big, hope for callers and don't stop studying the flop.
