Look for the good in every person and every situation. You'll almost always find it. - Brian Tracy

Optimism is the one quality more associated with success and happiness than
any other.

An average person who develops the habit of setting clear priorities and getting important tasks completed quickly will run circles around a genius who talks a lot and makes wonderful plans but gets very little done.

Perhaps the most important insight of all with regard to success is that to achieve greatly, you must become a different person. It is not the material things you accomplish or acquire that matter so much as it is the quality of the person you must become to accomplish well above the average. The development of self-discipline is the high road that makes everything possible for you.
