“If you can’t explain it simply, you don’t understand it well enough.”

Don't be intimidated by other people's opinions. Only mediocrity is sure of itself.

Time stays long enough for anyone who will use it.

The important thing is not what one is born with, but what they do with the gift of life.

The aim of a joke is not to degrade the human being, but to remind him that he is already degraded.

Have a heart that never hardens, and a temper that never tires.

You can complain because roses have thorns, or you can rejoice because thorns have roses.
