Nobody realises that speaking Malayalam is a big challenge for me.

The big challenge for me is that my nature is more towards comedy, so I understand when a comedy thing is working; I know when I'm not bored in a comedy.

I think that a lot of the most talented and driven people, they're not super deterred by failure. So if you put out a really big challenge, I think they get reality excited by that - they say, 'Hey, why not, let's go give it a shot, and if we fall short on that, at least we took a shot at doing something really important and meaningful.'

It's been my dream to race in F1 since I was eight. I don't see why that should change just because I've changed. It's a big challenge but I like to push myself. The accident has toughened me up and made me realise what's important. It's spurred me on to get to F1.

I like to see how other people work and be part of their stuff and see what I can do to be part of their worlds. Its a pretty big challenge, and that excites me.

I'm used to people not paying me a whole lot of attention and underestimating me and, frankly, for me a big challenge is to have people believe that I can be the president of the United States.

The whole, 'Is the Internet a good thing or a bad thing'? We're done with that. It's just a thing. How to maximise its civic value, its public good - that's the really big challenge.

It would be nice to make a movie that other people want to make, because every one of these movies, I basically have to find the only company in the world that's willing to make it, and it's always a big challenge. I end up spending a tremendous amount of energy and time trying to get money to make these movies and it's exhausting.

I did the Kilimanjaro climb a few years ago, then the six-day trek to Machu Picchu in Peru so this bike ride to raise money for Great Ormond Street seemed like the next big challenge.
