Essence of Life

The distance between insanity and genius is measured only by success?
The art of life is the art of avoiding pain.
To avoid sickness eat less; to prolong life worry less.
Every leader needs to look back once in awhile to make sure he has followers.
Life is a series of collisions with the future?
The part can never be well unless the whole is well?
Life's like a novel with the end ripped out.
Life is a long lesson in humility.
Life is full of obstacle illusion.
It is not hard to learn more. What is hard - is to unlearn what you have discover wrong! =D
