To win Test matches consistently you've got to take 20 wickets - yes, you've got to score runs but if you can't bowl a team out it doesn't matter how many runs you score.
Australia play best when they've got a bit of mongrel about them, when they play hard out in the middle, when they don't give an inch, when they play an aggressive brand of cricket.
The night before a game, I'd think about who I was playing, and then how I'd bowled against those guys, if I had got them out previously. While I was playing, I could recall nearly all my wickets and how I got the batsman out.
If you continually watch yourself do something well, it has a positive effect. If you sat down and watched yourself bowling, batting or fielding badly, it will probably have the equal effect.
My strength was probably more the mental side of the game rather than the skill side. I always had that self-belief that I was good enough. You have got to believe you are good enough, otherwise there is no point to it.
