The journey of a thousand miles begins with one step.

Believe you can and you're halfway there.
Strive not to be a success, but rather to be of value.
It does not matter how slowly you go as long as you do not stop.
I have not failed. I've just found 10,000 ways that won't work.
The best way to predict the future is to create it.
The only way to do great work is to love what you do.
The only thing necessary for the triumph of evil is for good men to do nothing.
Life is what happens when you're busy making other plans.
The only true wisdom is in knowing you know nothing.
The future belongs to those who believe in the beauty of their dreams.
Do not go where the path may lead, go instead where there is no path and leave a trail.

Be yourself; everyone else is already taken.
Success is not final, failure is not fatal: It is the courage to continue that counts.
The greatest glory in living lies not in never falling, but in rising every time we fall.
To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.

In the end, it's not the years in your life that count. It's the life in your years.
You miss 100% of the shots you don't take.

Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.
It always seems impossible until it's done.
