You’re playing chess.
It’s been a long day.
You’ve lost a few pieces.
Your chances of winning are slim.
Don’t despair.
Your lost pieces are sunk costs—there’s nothing you can do about them.
Don’t look back and chastise yourself for the errors.
Simply look ahead and focus on next best move available to you.
Real life is a lot like chess—except there are more second chances.
Our lives and littered with sunk costs and dead ends.
Don’t rue them.
Accept that they exist, and figure out the next best move.
