Pizza makes me think that anything is possible.

My dear friend, clear your mind of cant.

If I find 10,000 ways something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is another step forward.

Stand up to your obstacles and do something about them. You will find that they haven't half the strength you think they have.

It's all to do with the training: you can do a lot if you're properly trained.

Your pain is the breaking of the shell that encloses your understanding.

I don’t think we are going to become extinct. We are very clever and very resourceful.

We are citizens of the world. The tragedy of our times is that we do not know this.

A man should look for what is, and not what he thinks should be.

I'd rather be an optimist and a fool than a pessimist and right.

If you can accept losing, you can't win.

I am the captain of my soul.

To succeed in your mission, you must have single-minded devotion to your goal.

Our greatest glory is not in never falling but in rising every time we fall.

The meaning of life is that it is to be lived, and it is not to be traded and conceptualized and squeezed into a patter of systems.

Accept whatever comes to you woven in the pattern of your destiny, for what could more aptly fit your needs?

One person with a belief is equal to a force of ninety-nine who have only interests.

People who say it cannot be done should not interrupt those who are doing it.

We are what our thoughts have made us; so take care about what you think. Words are secondary. Thoughts live; they travel far.

The key to immortality is first living a life worth remembering.

Always remember you are braver than you believe, stronger than you seem, smarter than you think and twice as beautiful as you’ve ever imagined.
