Quote by Napoleon Hill
Great achievement is usually born of great sacrifice, and is never the result of selfishness.
A life of success and achievement is a direct result of utilizing the power of positive thinking.
Any great achievement is preceded by many difficulties and many lessons; great achievements are not possible without them.
What you get by achieving your goals is not as important as what you become by achieving your goals.
The most splendid achievement of all is the constant striving to surpass yourself and to be worthy of your own approval.
