He who knows that enough is enough will always have enough.

Anything that makes you weak physically, intellectually, and spiritually, reject as poison.,Swami Vivekanand

The wise man does not lay up his own treasures.

Imagination is more important than knowledge.

I have an almost complete disregard of precedent and a faith in the possibility of something better. It irritates me to be told how things always have been done. I defy the tyranny of precedent. I go for anything new that might improve the past.

Life is too short to dwell on what might have been.

I could not, at any age, be content to take my place by the fireside and simply look on.
