Advice is like snow; the softer it falls, the longer it dwells upon, and the deeper it sinks into the mind.
All difficult things have their origin in that which is easy, and great things in that which is small.
All human beings, by nature, desire to know.
Ralph Waldo Emerson
All life is an experiment.
An investment in knowledge always pays the best interest.
Dr. Albert Schweitzer
An optimist is a person who sees a green light everywhere. The pessimist sees only the red light. But the truly wise person is color blind.
Be not the first by whom the new are tried, nor yet the last to lay the old aside.
Be wiser than other people if you can, but do not tell them so.
Both poverty and riches are the offspring of thought.
Chance favors only those who court her.
