I cannot believe in the immortality of the soul... No, all this talk of an existence for us, as individuals, beyond the grave is wrong. It is born of our tenacity of life - our desire to go on living - our dread of coming to an end.

Just because something doesn`t do what you planned it to do doesn`t mean it`s useless.

Time is really the only capital that any human being has and the thing that he can least afford to waste or lose.

The best thinking has been done in solitude.

I have not failed. I`ve just found 10,000 ways that won`t work.
