Business is a game. Your job is a game. More to the point: money is a game. None of it is real.
It is a mistake to define your identity, your self-worth in economic terms. You are not your job or career; it is just a game you play. This game of acquiring money should be played like any other game. Just try to have fun, do your best to win, but make sure everyone else you're playing with is also having a good time.
Those who see the economic world as reality are those who lose. The true believers end up becoming the truly-exploited by losing sight of what truly matters. Play the game well, but don't take it so seriously.
