Believe that you can do it. Believing in oneself and having confidence are essential for achieving success.

To succeed in any environment, you have to believe in yourself. You must have an unshakable confidence in your own ability to achieve your goals and get the job done.

in order to succeed, we must first believe that we can.

BELIEVE IN YOURSELF! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy. But with sound self-confidence you can succeed. A sense of inferiority and inadequacy interferes with the attainment of your hopes, but self-confidence leads to self-realization and successful achievement.

the first step in achieving success is to firmly believe that you are an excellent person who deserves success.

You have to believe in yourself.

What I've found over almost four decades of studying success is that the most successful people in any field aren't just lucky. They have a different set of beliefs. They have a different strategy. They do things differently than everyone else.

You have to believe in yourself when no one else does. That’s what makes you a winner.

It is often contended that the belief that a person is solely responsible for his own fate is held only by the successful. This in itself is not so unacceptable as its underlying suggestion, which is that people hold this belief because they have been successful. I, for one, am inclined to think that the connection is the other way round and that people often are successful because they hold this belief. Though a man’s conviction that all he achieves is due solely to his exertions, skill, and intelligence may be largely false, it is apt to have the most benefi cial effects on his energy and circumspection. And if the smug pride of the successful is often intolerable and offensive, the belief that success depends wholly on him is probably the pragmatically most effective incentive to successful action; whereas the more a man indulges in the propensity to blame others or circumstances for his failures, the more disgruntled and ineffective he tends to become.

I believe in myself. I believe in those who work with me. I believe in my employer. I believe in my friends. I believe in my family. I believe that God will lend me everything I need with which to succeed if I do my best to earn it through faithful and honest service. I believe in prayer and I will never close my eyes in sleep without praying for divine guidance to the end that I will be patient with other people and tolerant with those who do not believe as I do. I believe that success is the result of intelligent effort and does not depend upon luck or sharp practices or double-crossing friends, fellow men or my employer. I believe I will get out of life exactly what I put into it, therefore I will be careful to conduct myself toward others as I would want them to act toward me. I will not slander those whom I do not like. I will not slight my work no matter what I may see others doing. I will render the best service of which I am capable because I have pledged myself to succeed in life and I know that success is always the result of conscientious and efficient effort. Finally, I will forgive those who offend me because I realize that I shall sometimes offend others and I will need their forgiveness.

Success comes from knowing that you did your best to become the best that you are capable of becoming.

Success is a state of mind. If you want success, start thinking of yourself as a success.

In order to succeed, you must know what you are doing, like what you are doing, and believe in what you are doing.
