People never improve unless they look to some standard or example higher or better than themselves.
Bernard M. Baruch
The art of living lies less in eliminating our troubles than in growing with them.
The biggest room in the world is the room for improvement.
There's only one corner of the universe you can be certain of improving, and that's your own self.
To change and to change for the better are two different things.
Henry Ward Beecher
Troubles are often the tools by which God fashions us for better things.
What is important is to keep learning, to enjoy challenge, and to tolerate ambiguity. In the end there are no certain answers.
What you get by achieving your goals is not as important as what you become by achieving your goals.
When a man is no longer anxious to do better than well, he is done for.
Charles F. Kettering
You can't have a better tomorrow if you are thinking about yesterday all the time.
You will find that the mere resolve not to be useless, and the honest desire to help other people, will, in the quickest and delicatest ways, improve yourself.
