Be a balanced optimist. Nobody is suggesting that you become an oblivious Pollyanna, pretending that nothing bad can or ever will happen. Doing so can lead to poor decisions and invites people to take advantage of you. Instead, be a rational optimist who takes the good with the bad, in hopes of the good ultimately outweighing the bad, and with the understanding that being pessimistic about everything accomplishes nothing. Prepare for the worst but hope for the best - the former makes you sensible, and the latter makes you an optimist.
Dale CarnegieAlways have something to say. The man who has something to say and who is known never to speak unless he has, is sure to be listened to.�
Dale CarnegieYou can't win an argument. You can't because if you lose it, you lose it; and if you win it, you lose it.
Dale CarnegieMen of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success.
Dale CarnegieGeorge Bernard Shaw was right. He summed it all up when he said: "The secret of being miserable is to have the leisure to bother about whether you are happy or not." So don't bother to think about it! Spit on your hands and get busy. Your blood will start circulating; your mind will start ticking-and pretty soon this whole positive upsurge of life in your body will drive worry from your mind. Get busy. Keep busy. It's the cheapest kind of medicine there is on this earth-and one of the best.
