Family is in town, so I give you a Presidents' Day cop-out:
"I find that friendship is like wine. It is raw when new. When riped with age it is the true old man's restorative cordial."
"Always bear in mind that your own resolution to succeed is more important than any other thing."
"Life is certainly only worthwhile as it represents a struggle for worthy causes. There is no struggle in perfect security. I am quite certain that the human being could not continue to exist if he had perfect security."
-Dwight D. Eisenhower
"Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'Press on' has solved and always will solve the problems of the human race."
"We have got but one life here.... It pays, no matter what comes after it, to try and do things, to accomplish things in this life, and not merely to have a soft and pleasant time."
