Adopt the motto: It doesn't matter who's right, but what's right.

Remember you will not always win. Some days, the most resourceful individual will taste defeat. But there is, in this case, always tomorrow - after you have done your best to achieve success today.

The un-happiest of mortals is that man who insists upon reliving the past, over and over in imagination - continually criticizing himself for past mistakes - continually condemning himself for past sins.

We simply must get it through our heads that holding a low opinion of ourselves is not a virtue, but a vice.

It is well known that when Thomas A. Eddison was stymied by a problem, he would lie down and take a short nap.

A step in the wrong direction is better than staying on the spot all our life. Once you're moving forward you can correct your course as you go. Your automatic guidance system cannot guide you when you're standing still.

Adopt the motto: It doesn't matter who's right, but what's right.
