In the end, you have to just pull the trigger. Trust the car, trust the brakes, just go.
On a bad day, I'll still have a conscious thing in my mind reminding me that what I think of as a bad day is still a very good day in probably 90% of the world's population's eyes.
Everything you can learn from is an opportunity to become stronger.
With racing, there's not one thing you need to be really strong at, it's a combination. You need a good base of cardio, good core, good neck strength. I think core and neck are the most important, but it's certainly not my favourite. Neck training is pretty boring.
Formula One was just cool. I loved racing, all types of racing, but from a young age, Formula One was the noise and everything, and that's what I was drawn to. I already knew when I was younger, the coolest guys are in F1... not that NASCAR drivers aren't cool, but that was always what I had in my head!
Since I got to F1, and especially since I got to Red Bull Racing, I said, 'I don't want to have any regrets. I've got a chance now in a top team. I want to leave it all on the table.'
In racing, things start coming up quicker, and the slipstream is stronger, so even judging in the mirrors how quick the cars are approaching isn't always easy.
I feel I am promoting the sport well in Australia with what I'm doing on an international level.
I used to go to work with Dad on the weekend. We'd drive past an indoor go-kart track every now and then, and we went there a few times. I was never tall enough, so I always left upset. I think I was seven when I was the right height, and I was like, 'Please let me have a go.' It was love at first sight.
Getting past my early 20s, I feel a bit more maturity and responsibility about that stuff. You get a good feeling from doing something good. You see a kid and you make his day, you realise the power of it. Whereas before, I was like, 'That's cool, whatever.' But now, that's what I'm most appreciative of.
Pretty much all the drivers I get on with, at least to say 'Hi' and have a conversation. But when the helmet's on, you don't care who it is. You have no sympathy: someone blows an engine in front of you, if it means you gain a position, then you're smiling.
