Echoes

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

I had ambition not only to go farther than anyone had done before, but as far as it was possible for man to go.

Nothing in life is so exhilarating as to be shot at without result.

Great deeds are usually wrought at great risks.

It seems to be a law of nature, inflexible and inexorable, that those who will not risk cannot win.

Difficulties are just things to overcome, after all.

I have learned to use the word 'impossible' with the greatest caution.

Ambition leads me not only farther than any other man has been before me, but as far as I think it is possible for man to go.

Take a step forward, lads. It will be easier that way.

A ship in harbor is safe, but that is not what ships are built for.

Kites rise highest against the wind, not with it.

Through hardship to the stars.

I whose ambition leads me not only farther than any other man has been before me, but as far as I think it possible for man to go.

It is hard to fail, but it is worse never to have tried to succeed.

Do just once what others say you can't do, and you will never pay attention to their limitations again.

Man needs difficulties; they are necessary for health.

Do you want to spend the rest of your life selling sugared water or do you want a chance to change the world?

Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to rank with those poor spirits who neither enjoy much nor suffer much, because they live in that grey twilight that knows neither victory nor defeat.

In prosecuting these discoveries, the dangers we are exposed to are obvious, but I rejoice that we are chosen to confront them.

It isn't all over; everything has not been invented; the human adventure is just beginning.

That which does not kill us makes us stronger.

Audacity succeeds as often as it fails; in life it has an even chance.

The depth of darkness to which you can descend and still live is an exact measure of the height to which you can aspire to reach.

I will either find a way or make one.

Difficulties strengthen the mind, as labor does the body.
