Growth itself contains the germ of happiness.

Sometimes we get sad about things and we don’t like to tell other people that we are sad about them. We like to keep it a secret. Or sometimes, we are sad but we really don’t know why we are sad, so we say we aren’t sad but we really are.

Success is not about the money you make, it's about the difference you make in people's lives.

The truth is always complicated, and it’s rarely pure.
