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 10 months, I was replaced from three films. That's when I realised I need to take my work seriously. It's a blessing I didn't get things easy. If I had, I wouldn't realise the value of success.

The film's success so far involves winning a couple of prizes at Cannes and Sundance, and getting some very nice reviews in newspapers and magazines. That hasn't had a big impact on my life yet.

Failure is easy to handle because once you fail, the options are very simple... like, 'Try something different,' or, 'Maybe if you do the same thing, do it in a different way.'

I've discovered over the years that being subject to both the adoration and the vilification actually makes me more disciplined. It makes me understand that it's the idea of writing a great book that propels me now, whereas it used to be the idea of success.
