/> Zain Khan must be the busiest 15-year old in Mumbai.

On Saturday night he's attending to his homework at 11.30 pm and has an early morning flight to catch to Delhi. "Then I'm back the next day to an inter-school competition. So yes, I'm pressed for time."

Before playing Hari Puttar Zain was seen sharing screen space with Rahul Bose in Chain Kuli To Main Kuli. Its failure didn't dampen Zain's spirits. "In life you win some you lose. Do I sound too mature for a 15-year old? Good na? It's better to grow up as fast as possible in today's world."

This 15-year old is not interested in doing the things kids normally do. "I'm already racing motorbikes and acting. That's not something other 15-year olds do. And I'm happy with that. I started riding when I was 5.

My dad also used to ride bikes. At the age of 2 I got keenly interested in bikes. Bikes are more excting than movies, more adventurous. Shooting is more....laidback and predictable. During the day you end up doing five shots over and over again."

Zain wants to be an actor and a motorbike racer when he grows up. "Do they sound like incompatible careers? That's fine. I want to be the different one. But my friends don't treat me special. They used to teat me differently.

But now that I've been doing ads and films for a while they's become used to me. But yes I did come across some jealousy and there were people who made loud nasty comments.

But you know what they say about dogs barking? I don't want to say it."

Hari Puttar took a while to complete. In-between Zain completed Chain Kuli Ki Main Kuli. "I'm now doing Ken Ghosh's film where I play Ziah Khan's brother and Shahid Kapoor's student.

I've also done a couple of serials and many ads. Does the work affect my studies? It does. But I make up for lost time. I prefer to study in the night when all is quiet and there're no distractions."

Ask him if working so hard at 15 is not abnormal and Zain shoots back, "I'm not Amitabh Bachchan. I'm not working that hard.

But yes, sometimes the workload does get too much and I tell my dad to get me a few days off. Otherwise I don't even get time to meet my friends. So I call them on the sets. We've lunch together, chat , play games."

At the moment Zain would rather focus on his board examinations. "I'm in Class 10. And I'm wondering how I'll work enough studies into my schedules. Best to leave it to God. I'm sure He has has plans for me. Like tonight I'm studying and I'll catch up on my sleep on flight to Delhi tomorrow."
