When you come to the end of your rope, tie a knot and hang on.

Science without religion is lame, religion without science is blind.

To dream of the person you would like to be is to waste the person you are.

I have no special talent. I am only passionately curious.

No tears in the writer, no tears in the reader. No surprise in the writer, no surprise in the reader.

I'm sick and tired of being sick and tired.

I look back on my life like a good day's work, it was done and I am satisfied with it.
