I always seem to have a vague feeling that he is a Satan among musicians, a fallen angel in the darkness who is perpetually seeking to fight his way back to happiness.

Happiness includes chiefly the idea of satisfaction after full honest effort. No one can possibly be satisfied and no one can be happy who feels that in some paramount affairs he failed to take up the challenge of life.

I know that I'm not the easiest person to live with. The challenge I put on myself is so great that the person I live with feels himself challenged. I bring a lot to bear, and I don't know how not to.

We are all one - or at least we should be - and it is our job, our duty, and our great challenge to fight the voices of division and seek the salve of reconciliation.

I'll co-host 'TODAY' from Los Angeles Saturday morning and then make my way up to Merced for that evening's graduation ceremony.
