There is no duty we so underrate as the duty of being happy. By being happy we sow anonymous benefits upon the world.
What we achieve inwardly will change outer reality.
By nature, man hates change; seldom will he quit his old home till it has actually fallen around his ears.
The art of progress is to preserve order amid change, and to preserve change amid order.
Things do not change; we change.
You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.
Time changes everything except something within us which is always surprised by change.
Change your thoughts and you change your world.
There is nothing permanent except change.
