It's important on any English wicket to leave well.
The fear of failing... not quite the fear of failing, but the uncertainty of whether you are going to perform or not, is there every single game I have played in my life. It will always be there.
There are lots of mentally very tough players that I have played against and with.
I believe I am strong mentally. My breaking points might be bigger than most players. I think it's because of the way I grew up with my two older brothers. They pushed my limits quite often - once every day, I think! I think that played a big role in my breaking point being bigger than most players. Not all players.
I like to entertain the crowd. Personally I like to entertain my team-mates first, but when the crowd gets going, it is amazing.
