"If you want to succeed you should strike out on new paths, rather than travel the worn paths of accepted success" — John Davison Rockefeller Rockefeller

Life belongs to the living, and he who lives must be prepared for changes.

Things do not change; we change

They must often change, who would be constant in happiness or wisdom

Medicine is my lawful wife and literature my mistress; when I get tired of one, I spend the night with the other.

If there is no struggle, there is no progress

He that will not apply new remedies must expect new evils; for time is the greatest innovator
