Probable impossibilities are to be preferred to improbable possibilities.

Impossible is just an opinion.

You better live your best and act your best and think your best today, for today is the sure preparation for tomorrow and all the other tomorrows that follow.

Do not think that what is hard for you to master is humanly impossible; but if a thing is humanly possible, consider it to be within your reach.

Man is a universe in little.

The positive thinker see the invisible, feels the intangible, and achieve the impossible.

The day will soon come when I will show the world that the transmission of power and speech without the aid of any wires is possible.

Free will, though it makes evil possible, is also the only thing that makes possible any love or good or joy worth having.
