A man's limitations are not the things he wants to do and can t; they are the things he ought to do but doesn't. The difficult we will do eventually, the impossible will just take a little more time.

In dreams and love there are no impossibilities.

Man can believe the impossible, but man can never believe the improbable.

Apparently there is nothing that cannot happen today.

The Difficult is that which can be done immediately; the Impossible that which takes a little longer.

It is not a lucky word, this name ''impossible''; no good comes of those who have it so often in their mouths.

Impossible is a word only to be found in the dictionary of fools.

Nothing in this world is impossible to a willing heart.

You must do the thing that you think you cannot do.

All who have accomplished great things have had a great aim, have fixed their gaze on a goal which was high, one which sometimes seemed impossible.
