All men have the same defect: they wait to live, for they have not the courage of each instant.

The fundamental defect of fathers, in our competitive society, is that they want their children to be a credit to them.

I have some experience with parents who turn a blind eye to their kids' shortcomings: I am related to a few of them.

But magnetic propulsion has some drawbacks.

Without imperfection, you or I would not exist.
