I never doubted my ability,but when you hear all your life you're inferior,it makes you wonder if the other guys have something you've never seen before. If they do,I'm still looking for it.
-Hank Aaron

Pretend that every single person you meet has a sign around his or her neck that says,'Make me feel important.' Not only will you succeed in sales,you will succeed in life.
-Mary Kay Ash

One important key to success is self-confidence. An important key to self-confidence is preparation.
-Arthur Ashe

You have to believe in yourself,that's the secret. Even when I was in the orphanage,when I was roaming the street trying to find enough to eat,even then I thought of myself as the greatest actor in the world. I had to feel the exuberance that comes from utter confidence in yourself. Without it,you go down to defeat.
-Charlie Chaplin

A foolish consistency is the hobgoblin of little minds,adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think now in hard words,and to-morrow speak what to-morrow thinks in hard words again,though it contradict every thing you said to-day. -- `Ah,so you shall be sure to be misunderstood.' -- Is it so bad,then,to be misunderstood? Pythagoras was misunderstood,and Socrates,and Jesus,and Luther,and Copernicus,and Galileo,and Newton,and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.
-Ralph Waldo Emerson,Self Reliance,1841

"Don't let life discourage you; everyone who got where he is had to begin where he was."
-Richard L. Evans

"Whether you believe you can do a thing or not,you are right."
-Henry Ford

There are admirable potentialities in every human being. Believe in your strength and your youth. Learn to repeat endlessly to yourself,'It all depends on me'.
-André Gide

Somebody said that it couldn't be done,
But he with a chuckle replied
That "maybe it couldn't," but he would be one
Who wouldn't say so till he'd tried.
So he buckled right in with the trace of a grin
On his face. If he worried he hid it.
He started to sing as he tackled the thing
That couldn't be done,and he did it.
-Edgar A. Guest,from "It Couldn't Be Done"

Courage must come from the soul within,
The man must furnish the will to win.
So figure it out for yourself,my lad.
You were born with all that the great have had,
With your equipment they all began,
Get hold of yourself and say: "I can."
-Edgar A. Guest,from the poem "Equipment"

We can never really be prepared for that which is wholly new. We have to adjust ourselves,and every radical adjustment is a crisis in self-esteem: we undergo a test,we have to prove ourselves. It needs inordinate self-confidence to face drastic change without inner trembling.
-Eric Hoffer

"When you are content to be simply yourself and don't compare or compete,everybody will respect you."
-Lao-Tzu

"Who has confidence in himself will gain the confidene of others."
-Leib Lazarow

"If being an egomaniac means I believe in what I do and in my art or music,then in that respect you can call me that ... I believe in what I do,and I'll say it."
-John Lennon

If you think about disaster,you will get it. Brood about death and you hasten your demise. Think positively and masterfully,with confidence and faith,and life becomes more secure,more fraught with action,richer in achievement and experience.
-Edward Rickenbacker

"A great deal of talent is lost to the world for want of a little courage. Every day sends to their graves obscure men whose timidity prevented them from making a first effort."
-Sydney Smith

Fast is fine,but accuracy is everything.
-Xenophon.
