Like the mistake of equating business with war (pick up the nearest Sun Tzi reference in your next business self-help book), we make the mistake of comparing life as a game of chess.
This is as misguided as thinking your wife loves you like you love her.
Chess game ends, sometimes pretty quickly. Life, like Tetris, goes on. When you fail, the game continues from scratch.
Chess has no fog-of-war, everybody gets a god-view of the battleground. Life is surrounded by fogs of every kind. Like Tetris, you only get to see what's coming next.
In chess you have an enemy. In Tetris, you're playing against yourself. In life, you are your own biggest enemy.
Life is additive like Tetris blocks, the longer you play, the 'richer' you get. In chess, you pieces are designed disappear as the game goes.
Your aim in life isn't to take away the other guy's king. As soon as you go do the game ends. That's scarcity-thinking.
Your aim in life is to let the blocks stack, manage, and then promptly discard them when the time comes. After that, the game goes on. But it's not the same game; it's faster and you're a new person reborn with better power and skills.
The game isn't to win. The game is to keep playing.
