There is only one corner of the universe you can be certain of improving, and that's your own self.

If you wish to achieve worthwhile things in your personal and career life, you must become a worthwhile person in your own self-development.
The safest principle through life, instead of reforming others, is to set about perfecting yourself.
I do not think much of a man who is not wiser today than he was yesterday.
People seldom improve when they have no other model but themselves to copy.

Progress is impossible without change; and those who cannot change their minds cannot change anything.
Unless you try to do something beyond what you have already mastered, you will never grow.
Hold yourself responsible for a higher standard than anybody expects of you. Never excuse yourself.

Those who seek a better life must first become a better person.

Each of us must work for his own improvement, and at the same time share a general responsibility for all humanity.
If you don't like something, change it. If you can't change it, change your attitude.
Formal education will make you a living; self-education will make you a fortune.
