No one does anything right in life, until they realize that they are making a mistake

The truth of a theory is in your mind, not in your eyes.

I am enough of an artist to draw freely upon my imagination.

I know what it's like to see one's mother go through the agony of death and be unable to help; there is no consolation. We all have to bear such heavy burdens, for they are unalterably linked to life.

You do not really understand something unless you can explain it to your grandmother.

If you do the same thing over and over again you cannot ever expect a different outcome.

It is impossible to get anywhere without sinning against reason.
