In life, there are always intense battles, and yet we must practise the lessons from the Gita.

I always practise penalties, but what people don't understand is that you can never recreate that pressure situation that you're under.

When I was a kid, I'd practise Chopin on piano - and I love Chopin! He's my dawg! Then I'd go out on the stoop and blast the radio. I'm from New York, the concrete jungle. Hip-hop influenced me from day one.

When I practise scales I will play four notes on one string. If I'm playing a C major scale, starting on F, I'll play the F, G, A, and B on one string and the C will be on the A string, etc, etc. Because I found not only was it good for my hands but it was really good for interconnecting things.

When I first began learning yoga, I found it really hard because I couldn't clear my mind for the meditative part of it, but then after a few weeks it became easier and I could see how it began to change my body. I became more flexible and more relaxed and at peace with my environment. I love yoga and I encourage all my friends to practise it.

You want to ensure people can do it right 99 percent of time. When we have to fire one of our surgical trainees, it is never because they don't have the physical skills but because they don't have the moral skills - to practise and admit failure.
