So many of our dreams at first seem impossible. Then they seem improbable. And then, when we summon the will, they soon become inevitable.

This is the mark of a really admirable man: steadfastness in the face of trouble.

There is no chance, no destiny, no fate, Can circumvent or hinder or control. The firm resolve of a determined soul. Gifts count for nothing; will alone is great; All things give way before it, soon or late.

The thought of only being a creature of the present and the past was troubling. I longed for a future, too, with hope in it. The desire to be free, awakened my determination to act, to think, and to speak.

Impossible is just an opinion.

All good writing is swimming under water and holding your breath.

I dream, I test my dreams against my beliefs, I dare to take risks, and I execute my vision to make those dreams come true.

Never give up on a dream just because of the time it will take to accomplish it. The time will pass anyway.

Remember your dreams and fight for them. There is just one thing that makes your dream become impossible:the fear of failure.

Tell me not, in mournful numbers, Life is but an empty dream!

Now, I say to you today my friends, event though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream. I have a dream that one day this nation will rise up and live out the true meaning of its creed: “We hold these truths to be self-evident, that all men are created equal.

Never give up on what you really want to do. The person with big dreams is more powerful than one with all the facts.

It's the possibility of having a dream come true that makes life interesting.

Man can learn nothing unless he proceeds from the known to the unknown.

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

There will be obstacles. There will be doubters. There will be mistakes. But with hard work, there are no limits.

The only impossible journey is the one you never begin.
