Many people think that if they were only in some other place, or had some other job, they would be happy. Well, that is doubtful. So get as much happiness out of what you are doing as you can and don't put off being happy until some future date.

If we rail and kick against it and grow bitter, we won't change the inevitable; but we will change ourselves. I know. I have tried it. I once refused to accept an inevitable situation with which I was confronted. I played the fool and railed against it, and rebelled. I turned my nights into hells of insomnia. I brought upon myself everything I didn't want. Finally, after a year of self-torture, I had to accept what I knew from the outset I couldn't possible alter.

...Be grateful for what you have to be thankful for instead of complaining about the little things that annoy you.

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.

'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 .
