When I'm on my own, I can be negative. I need my friends and family around to help pick me up if I've had a bad qualifying session. I think insecurity plagues a lot of sportspeople.

I keep my weight low, although you need to be able to move your weight around the race car to change the balance. I'm 6ft and I'm 70kg so I haven't much fat on me.

I've spent as much as 30 grand on a watch but it's not about flaunting my wealth. I don't have many extravagances but watches are my biggest one. I must have 30 of them now. I've been collecting since the age of nine, when I won a black TAG in a karting event.

I need to develop a car and engineer a car in a position that feels comfortable for me, and I don't think anyone can do a better job than I can in that position. The problem for me is if I can't get the car there I do struggle more than some.

I think fans of the sport have a good understanding now of how fit Formula One drivers need to be.

My time at Honda was amazing. Some of my best times in Formula One, actually. I might not have won races, just one race, but I had a lot of fun.

The fast, flowing parts, the high-speed corners, that's where a Formula One car is at its best - changes of direction, pulling high g-forces left and right.
