Real improvement is of slow growth only.
Seneca
To improve is to change; to be perfect is to change often.
Winston Churchill
Our lives improve only when we take chances - and the first and most difficult risk we can take is to be honest with ourselves
Walter Anderson
The first step to improvement, whether mental, moral, or religious, is to know ourselves - our weakness,errors, deficiencies, and sins, that, by divine grace, we may overcome and turn from them all
Tryon Edwards
Judge of thine improvement, not by what thou speakest or writest, but by the firmness of thy mind, and the government of thy passions and affections.
Thomas Fuller
Improvement makes straight roads; but the crooked roads without improvement are roads of genius.
William Blake
Men are anxious to improve their circumstances, but are unwilling to improve themselves.
James Allen
Retire into yourself as much as possible. Associate with people who are likely to improve you. Welcome those whom you are capable of improving. The process is a mutual one. People learn as they teach.
Lucius Annaeus Seneca
There is only one corner of the universe you can be certain of improving, and that's your own self.
Aldous Huxley
Humankind is made up of two sexes, women and men. Is it possible for humankind to grow by the improvement of only one part while the other part is ignored? Is it possible that if half of a mass is tied to earth with chains that the other half can soar into skies?
Mustafa Kemal Atatrk
Man will only become better when you make him see what he is like.
Anton Pavlovich Chekhov
All change is not growth as all movement is not forward.
Ellen Glasgow
It is natural human impulse to think of evolution as a long chain of improvements, of a never-ending advance towards largeness and complexity in a word, towards us. We flatter ourselves. Most of the real diversity in evolution has been small-scale. We large things are just flukes an interesting side branch.
William Cullen Bryant
