When someone says, 'How long do you see yourself captaining for?' you don't really know.
Relief isn't quite the right word but there's satisfaction at a job well done and I'm proud to say that I'm an Ashes-winning captain. Without taking it too personally, it has a nice little ring to it.
The most important opinions to me are those that belong to the guys in the changing room.
The beauty of cricket is that there are so many different opinions as to the best way to do something and at times it is easier to see something when you're not emotionally involved in the game and not responsible for the decision. You can go and have a cup of tea and look at it from a different point of view.
The biggest thing was probably a better understanding of the mental side of cricket and also the technical challenges I have in my game. Those two things happened in a very short space of time which changed me as a player.
I think my general view of day-night Test cricket is that there is definitely something there that the ICC can keep looking at because it moves the game forward with timing and allows more people to come and watch.
That is one of the great things about Test cricket, the ball. Sometimes it swings conventionally, sometimes it doesn't and sometimes it reverses.
You need to come to terms with the fact that you are not an international cricketer anymore and that's certainly difficult to come to terms with. But then I love going to my farm and spending time with my family. Drop and pick up my kids from school and play cricket as well.
If you have lost matches and not played to potential, criticism will come your way. Critics and media will say what they see and take you on. They will say things which you might not like to hear. But that's professional sport.
It is frustrating when you go all that way, you train, and you just don't turn up. It does happen. If you play 100-odd Test matches, there's going to be little periods when you don't score the runs.
