Try to become not a man of success, but try rather to become a man of value.

What's money? A man is a success if he gets up in the morning and goes to bed at night and in between does what he wants to do.

He who wishes to be rich in a day will be hanged in a year.

History is full of people who out of fear, or ignorance, or lust for power have destroyed knowledge of immeasurable value which truly belongs to us all. We must not let it happen again.

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.

I have no idea [what my IQ is]. People who boast about their IQ are losers.

For millions of years, mankind lived just like the animals. Then something happened which unleashed the power of our imagination. We learned to talk and we learned to listen. Speech has allowed the communication of ideas, enabling human beings to work together to build the impossible. Mankind's greatest achievements have come about by talking, and its greatest failures by not talking. It doesn't have to be like this. Our greatest hopes could become reality in the future. With the technology at our disposal, the possibilities are unbounded. All we need to do is make sure we keep talking. British Telecom advertisement (1993).
