Our prime purpose in this life is to help others. And if you can't help them, at least don't hurt them.

I believe that the very purpose of life is to be happy. From the very core of our being, we desire contentment. In my own limited experience, I have found that the more we care for the happiness of others, the greater is our own sense of well-being.

We think about having this global community, but the social fabric that we have is not one big community. It is millions of small communities and social structures and families that exist - that are really the things that we turn to for our personal and emotional and spiritual needs. And that gives us our sense of hope and purpose in life.

There used to be a huge hole in my life that I wrote many albums about. I didn't realise it was a wife-and-daughter-shaped hole. They've plugged that gap. Everything I do, I do for them now. When daddy goes to work, it's daddy going to work, not Rob going to work. I feel like there's a purpose to everything.

Everything in life got its purpose, find its reason in every season.

My main purpose in life is to make money so I can afford to go on creating more inventions.
