We should not hesitate too much during the first half of our lives, while we should not regret at what we’ve done during the other half. We should seize every opportunity to find a way out in our lives, for it goes off swiftly. We should say something urgent slowly, something serious clearly, something small humorously and something unsure cautiously. We should never say something that did not happen, something that you cannot do, something that does harm to others, and something that is disgusting. We should tell others our happiness in specific occasions and should not tell anyone our unhappiness. Do not easily say something about others. We should follow our own heart and interest, and fulfill what we should do instead of merely paying lip service and looking forward to the future.
