The greatest glory in living lies not in never falling, but in rising every time we fall.

Life is like riding a bicycle. To keep your balance, you must keep moving.

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

A man is but the product of his thoughts. What he thinks he becomes.

Life isn't about finding yourself. Life is about creating yourself.

Without music, life would be a mistake.

I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

Only a life lived for others is a life worthwhile.
