“Wisdom outweighs any wealth”

“A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing”

“Always bear in mind that your own resolution to succeed, is more important than any other one thing”

“Success is to be measured not so much by the position that one has reached in life as by the obstacles which he has overcome while trying to succeed.”

“If I were to name the three most precious resources of life, I should say books, friends, and nature; and the greatest of these, at least the most constant and always at hand, is nature”

“Literature is an investment of genius which has dividends to all subsequent times”
