“Women. They are a complete mystery.”

Science can explain the universe without the need for a Creator.

In fact, once he is motivated no one can change more completely than the man who has been at the bottom. I call myself the best example of that.

It’s always difficult for anyone trying to compete against their past achievements.

You cannot wait for someone to save you, to help you, to complete you. No one can complete you. You complete yourself.

Never ever compete on prices, instead compete on services and innovation.

Obscurity and a competence – that is the life that is best worth living.

The most terrifying thing is to accept oneself completely.
