The world changes. The world is completely different now from when I was growing up. Back then, you didn't say things like they say now, out loud, about race and things. But that's just progress. When are we going to find out that we're all the same - we're all absolutely, without a doubt, the same?

I've lost a few notes on the top. But I've gained a little insight about what makes people comfortable when they're listening or watching a performance of mine. It usually has to do with singing something that isn't vocally too strenuous.

I'm still going strong. I have been very blessed and still am. I love singing. Obviously, at my age, I don't tour with as many dates throughout the year as I did in the past. But I do this to honor my father who was also a singer. I still miss him and his encouragement.

Even though there's no forum for me on the radio for the kind of music I sing anymore, I am still excited about having a career where I can sing the best music in the world, and people will come and hear me because of the hit records I've had in the past.

In my experience, being busy and working hard is the key to sanity/happiness.

It is the ultimate luxury to combine passion and contribution. It's also a very clear path to happiness.

When you care about people's happiness and productivity, you give them what brings out the best in them and their creativity. And if you give them a choice, they'll say, 'I want an iPhone,' or 'I want a Mac.' We think we can win a lot of corporate decisions at that level.

I would be the first to say that while a lack of money can cause misery, money doesn't buy you happiness.
