All things flow, nothing abides.
You cannot step into the same river twice, for the waters are continually flowing on.
Nothing is permanent except change.

Heraclitus

Gilgamesh, whither are you wandering?
Life, which you look for, you will never find. For when the gods created man, they let death be his share, and life withheld in their own hands. Gilgamesh, fill your belly, day and night make merry, let days be full of joy, dance and make music day and night. And wear fresh clothes, and wash your head and bathe. Look at the child that is holding your hand, and let your wife delight in your embrace. These things alone are the concern of men.
God

The clock of life is wound but once, and no man has the power to tell just when the hands will stop, at late or early hour. Now is the only time you own. Live, love, toil with a will. Place no faith in time. For the clock may soon be still

Real estate cannot be lost or stolen, nor can it be carried away.
Purchased with common sense, paid for in full, and managed with reasonable care,
it is about the safest investment in the world. 
Franklin D. Roosevelt

 Any man regardless of colour, will be recognized and rewarded in the proportion as he learns something well - learns to do it better than some one else. I believe my race will succeed in the proportion as it learns to do common things in uncommon manner; learns to do a thing so thoroughly that no one can improve upon what has been done; learns to make its service of indispensable value. 
Booker T Washington

I know men in the ranks, who are going to stay in the ranks,
why, because they haven't the ability to get things done!
Dale Carnegie

I'm a great believer in luck, and I find the harder I work, the more I have of it.
