I really enjoy (and highly recommend) the Tactics Time newsletter by Tim Brennan. A few times each week, he sends an email with a tactical conundrum from a real game, something that you might actually see over the board--not just tactical compositions. He also includes a little bit of interesting commentary on the game itself.
Each newsletter features an inspirational quote. I wanted to share a few of my favorites.
"In chess, attention is more important than concentration." - Frank J. Marshall
"When you strike at a king, you must kill him" - Ralph Waldo Emerson
"All great achievements require time." ― Maya Angelou
"Tactics are it. People under 2000 shouldn't study anything else. You need to work on the ability to count and calculate." - Mig Greengard
"Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful people with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'press on' has solved and always will solve the problems of the human race." - Calvin Coolidge
"The weaker the player the more terrible the Knight is to him, but as a player increases in strength the value of the Bishop becomes more evident to him, and of course there is, or should be, a corresponding decrease in his estimation of the value of the Knight as compared to the bishop." - Jose Capablanca
"I give 98 percent of my mental energy to Chess. Others give only 2 percent." - Bobby Fischer
"The pleasure to be derived from a chess combination lie in the feeling that a human mind is behind the game, dominating the inanimate pieces ...and giving them breath of life." - Richard Reti

"When you see a good move, look for a better one." - Emanuel Lasker
"The player who plays best in a tournament never wins first. He finishes second behind the guy with the most luck." - Saviely Tartakower
"There are only two kinds of moves in the opening: moves which are wrong and moves which could be wrong." - Saviely Tartakower
"Improvise. Adapt. Overcome." - Clint Eastwood (Heartbreak Ridge)
