Seek, above all, for a game worth playing. Such is the advice of the oracle to modern man. Having found the game, play it with intensity -- play as if your life and sanity depended on it. (They do depend on it.) Follow the example of the French existentialists and flourish a banner bearing the word "engagement." Though nothing means anything and all roads are marked "NO EXIT," yet move as if your movements had some purpose. If life does not seem to offer a game worth playing, then invent one. For it must be clear, even to the most clouded intelligence, that any game is better than no game. - ROBERT S. DE ROPP, "THE MASTER GAME"
Even without comparing ourselves to the world's greatest, we set such high standards for ourselves that neither we nor anyone else could ever meet them - and nothing is more destructive to creativity than this. We fail to realize that mastery is not about perfection. It's about a process, a journey. The master is the one who stays on the path day after day, year after year. The master is the one who is willing to try, and fail, and try again, for as long as he or she lives. - George Leonard, "Mastery".
If you are still hung up on achieving the impossible, remember that at the flip of a switch you can relive reality as often as it takes to prove to yourself that there is no absolutely perfect way to do anything. So give it a go. Say it slowly; Absolute perfection does not exist. - Susan Halden-Brown, "Mistakes Worth Making".

If the map doesn't agree with the ground, then the map is wrong. - Gordon Livingston, "Too Soon Old, Too Late Smart".

“If you are going to try, go all the way or don't even start. If you follow it you will be alive with the gods. It is the only good fight there is.” ― Charles Bukowski
An emphasis on winning limits you and cheats you of some of your potential... You can't win all the time, but you can always work on becoming better. And as you do, winning will take care of itself. - Kenneth Baum, "The Mental Edge".
