I confess that in 1901 I said to my brother Orville that man would not fly for fifty years.
You'll never get ahead of anyone as long as you try to get even with him.
Only those are fit to live who do not fear to die; and none are fit to die who have shrunk from the joy of life and the duty of life. Both life and death are parts of the same Great Adventure.
I think nature's imagination Is so much greater than man's, she's never going to let us relax.
Though the road's been rocky it sure feels good to me.
I love those who can smile in trouble...
Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.
Only in the darkness, you are able to see the stars.
Man needs his difficulties because they are necessary to enjoy success.
I don't think necessity is the mother of invention. Invention ... arises directly from idleness, possibly also from laziness. To save oneself trouble.
Always do what you are afraid to do.
Write it on your heart that every day is the best day in the year.
People should pursue what they're passionate about. That will make them happier than pretty much anything else.
I'm sorry I wrote you such a long letter; I didn't have time to write a short one.
Patience is bitter, but its fruit is sweet.
I am not bound to win, but I am bound to be true. I am not bound to succeed, but I am bound to live by the light that I have. I must stand with anybody that stands right, and stand with him while he is right, and part with him when he goes wrong.
Life isn't about finding yourself. Life is about creating yourself.
No one is free who has not obtained the empire of himself. No man is free who cannot command himself.
If you spend too much time thinking about a thing, you'll never get it done.
Nothing great was ever achieved without enthusiasm.
The crisis of today is the joke of tomorrow.
