To improve rapidly, don't play. Study.
also, Always attack where your pawns are pointing.
Fischer said "Don't give up... even if you're in big trouble... Chess is a kaleidoscope- it's ever changing- ...and opportunities suddenly appear."
You can find it here along with some other tips:

1) the difference when you're playing someone around your strength is how much you want to win
2)the more you play focused chess (not blitz, blitz is for fun), the stronger you become.
3) Get a good mentor
4) Analyze your games
5) If you want to practice, play semi-rapid chess (not blitz) and check the opening theory right after each game
6) Don't fear your opponent's rating when playing : if it's higher than yours, then, stir up trouble on the chessboard.
7) Most strong players don't read many chess books. They pick what they need as a given time and set positions on the board to analyze.
8) Have you chess brain work at least 10 minutes every day
Play defensively until your oponent makes a big mistake.
Who said that one, Karpov?
I like, "play the board not the person" of course, in top level competition they play the person too, but as an amateur I just have to play the best moves I can find :)
Always look at the possible checks on the board first before anything else.
If your less then 1600 focus on reducing blunders. If your greater then 1600 focus on tactics.
When you see a check, always play it. It might be mate!
Thats not good advice! Only play a check if it strengthens your position.

I thought that was Capablanca. And that's also a statement that sounds better than it actually is. Even Capa would have to look several moves ahead when forced to..
