Every rope has two ends; you must hold it by both.
Lose less when you lose, win more when you win.
A professional player is someone who, when a losing streak hits, is no longer playing.
It's better to play small, but with large chips.
Playing small means aiming for a modest percentage gain, relative to the total bankroll.
Playing big means trying to win a large percentage of the total bankroll.
A professional plays with big chips—but playing with big chips doesn't make you a professional.
