We should be careful of our actions in life, just as a person playing chess thinks carefully before making any move. Always weigh what you are planning, to see if you might later regret your move.
In a game of chess, which has no major ramifications in a person’s life whether he wins or loses, each player takes much time to think of every alternative and weigh its consequences. All the more so in daily behavior, always think before speaking or taking action. We have much more to gain or lose and should at least be as patient as when playing chess.
