One of the worst features about worrying is that it destroys our ability to concentrate. When we worry, our minds jump here and there and everywhere, and we lose all power of decision. However, when we force ourselves to face the worst and accept it mentally, we then eliminate all those vague imaginings and put ourselves in a position in which we are able to concentrate on our problem.
Dale CarnegieBe 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 Carnegie'When you have a lemon, make a lemonade.' That is what a great educator does. But the fool does the exact opposite. If he finds that life has handed him a lemon, he gives up and says, 'I 'm beaten. It is fate. I haven't got a chance.' Then he proceeds to rail against the world and indulge in an orgy of self-pity .
