If I had it [life] to do all over again, I'd have been a plumber.

Time has no independent existence apart from the order of events by which we measure it.

The attempt to combine wisdom and power has only rarely been successful and then only for a short while.

As I look back over the truly crucial events in my life I realize that they were not planned long in advance. Albert Einstein said, 'There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is.'

The world as we see it is only the world as we see it. Others may see it differently.

The only way to escape the corruptible effect of praise is to go on working.

Time does not exist - we invented it
