My challenge over the next few weeks is to start putting in the match-winning performances in limited-overs cricket that I have done in Tests over the last 18 months. I want to play as well as I know I can in the shorter forms of the game.
I've shown people in Test matches when we've stepped up through the gears that I can play all the shots: the reverse-sweeps, hitting over the top - I've got all the shots to do it, so it's just about improving now.
I've played just seven Twenty20 games for England but I've played 97 one-day internationals, so I'm working my way towards the status of an experienced player, and I've had good times in that form of the game - I got Man of the Series last time India were here in 2007 - but my consistency has to go up a little bit.
With an average of 35, I've got a decent record in one-day cricket but I'd like to make it an excellent record and the way to do that is to convert the sixties, seventies and eighties into big hundreds - as I've been doing in Test matches.
Before the one-dayers start against Sri Lanka at The Oval on Tuesday, we've got the only Twenty20 game of the summer against them at Bristol tomorrow, and let's hope Stuart Broad is fit to captain the team for the first time in that game. With the new structure in place - Andrew Strauss staying as Test captain with Alastair Cook and Broady as 50-over and T20 captains respectively - these are really exciting times and there is a lot to look forward to for English cricket.
I've had some experience of captaining Warwickshire in four-day and 40-over games - including winning the CB40 Final at Lord's last year - and there is a slight difference in your approach to your team-mates when you're leading, but you don't have to change too much, because you lead by what you do on the field.
You're possibly a bit nervous. I certainly was before the Lord's final, because you might only get one opportunity to do that so you want to make sure everything is right, and, whether he's captain for the first time tomorrow or later in the summer, I'm sure Broady will be nervous, too.
But he'll have the backing of the whole England dressing room and everyone is excited.
Whether you're full-time captain or whether you're just doing it temporarily, you want to put your own stamp on things, make your own decisions - that's part of captaincy.
You have to try to inspire players to perform at a good level or, in big games, above what they're usually capable of doing, and I really enjoyed the challenge.
Twenty20 is pretty frenetic so, as captain, you need your players to know exactly what they're doing.

You need to think quickly on your feet, which I'm sure Broady will be able to do and it's about making your plans work under pressure.
Broady is someone with a very good cricket brain, who really carries himself well on the field and has an aura about him that opposition players notice. It's exciting to have someone like him to take Twenty20 forward.
