We are all in the gutter, but some of us are looking at the stars.

You see things; you say, 'Why?' But I dream things that never were; and I say 'Why not?

The best way out is always through.

Dare to live the life you have dreamed for yourself. Go forward and make your dreams come true.

I confess that in 1901 I said to my brother Orville that man would not fly for fifty years.

The way I see it, if you want the rainbow, you gotta put up with the rain.

A long apprenticeship is the most logical way to success. The only alternative is overnight stardom, but I can't give you a formula for that.

Sincerity and truth are the basis of every virtue.

Some people feel the rain. Others just get wet.

If you paint in your mind a picture of bright and happy expectations, you put yourself into a condition conducive to your goal.

Once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.

The only way of finding the limits of the possible is by going beyond them into the impossible.

You shape your own destiny.

I believe that if you show people the problems and you show them the solutions they will be moved to act.

It marks a big step in your development when you come to realize that other people can help you do a better job than you could do alone.

The people who were trying to make this world worse are not taking the day off. Why should I?

Start by doing what is necessary, then what is possible, and suddenly you are doing the impossible.

The only way of discovering the limits of the possible is to venture a little way past them into the impossible.

Happiness depends more on the inward disposition of mind than on outward circumstances.

Above all things, respect yourself.

My heroes are the ones who survived doing it wrong, who made mistakes, but recovered from them.
