Success is not a miracle. Nor is it a matter of luck. Everything happens for a reason, good or bad, positive or negative.

You are where you are and what you are because of yourself, nothing else. Nature is neutral. Nature doesn't care. If you do what other successful people do, you will enjoy the same results and rewards that they do. And if you don't, you won't.

There is a direct relationship between your own level of self-esteem and the health of your personality. The more you like and respect yourself, the more you like and respect other people. The more you consider yourself to be a valuable and worthwhile person, the more you consider others to be valuable and worthwhile as well. The more you accept yourself just as you are, the more you accept others just as they are.

Luck is predictable; the harder you work, the luckier you get.

The key of success is for you to set one big, challenging goal and then to pay any price, overcome any obstacle and persist through any difficulty until you finally achieve it
