Success is the maximum utilization of the ability that you have.
-- Zig Ziglar
The great breakthrough in your life comes when you realize that you can learn anything you need to learn to accomplish any goal that you set for yourself. This means there are no limits on what you can be, have, or do.
-- Brian Tracy
Success is going from failure to failure without losing your enthusiasm.
-- Winston Churchill
"I cannot do it" never produced anything.
"I will try" has performed wonders.
The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather in a lack of will.
-- Vincent T. Lombardi
