The foundation of lasting self-confidence and self esteem is excellence, mastery of your work.
I do the very best I know how, the very best I can, and I mean to keep on doing so until the end.
The noblest search is the search for excellence.
Lyndon B. Johnson
Excellence always sells.
Excellence encourages one about life generally; it shows the spiritual wealth of the world.
Not to be cheered by praise, not to be grieved by blame, but to know thoroughly one's own virtues or powers are the characteristics of an excellent man.
A superior man is modest in his speech, but exceeds in his actions.
Whatever you do, don't do it halfway.
If you want to achieve excellence, you can get there today. As of this second, quit doing less-than-excellent work.
Thomas J. Watson
When you are tough on yourself, life is going to be infinitely easier on you.
The secret of living a life of excellence is merely a matter of thinking thoughts of excellence. Really, it's a matter of programming our minds with the kind of information that will set us free.
Charles R. Swindoll
We need to internalize this idea of excellence. Not many folks spend a lot of time trying to be excellent.
President Barack Obama
Always be getting and doing better. Never settle for mediocrity.
Robin Sharma, The Greatness Guide
To achieve our personal best, we must overcome incorrect beliefs, many of which have been imprinted and reinforced ever since third grade.
Henry Marsh, The Breakthrough Factor
