Patriotism is your conviction that this country is superior to all other countries because you were born in it.
There are admirable potentialities in every human being. Believe in your strength and your youth. Learn to repeat endlessly to yourself, 'It all depends on me.'
Whatever you do, do it to the purpose; do it thoroughly, not superficially. Go to the bottom of things. Any thing half done, or half known, is in my mind, neither done nor known at all. Nay, worse, for it often misleads.
Mediocrity knows nothing higher than itself, but talent instantly recognizes genius.
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.
Humor is also a way of saying something serious.
If you aren't fired with enthusiasm, you will be fired with enthusiasm.
