Previous World Cups I've played in have left me with a sense of unfinished business from both a team and individual point of view.
I first went to the 2003 tournament in South Africa and Kenya as a youngster and played only one game. It was a great experience, particularly watching Stephen Fleming scoring an impressive hundred against South Africa at a deafening Wanderers, but we missed out on the semifinals because we refused to play in Kenya. If we hadn't refused, who knows how far we could have gone in the tournament, but it was the only decision to make after the threats flying around.
I missed the 2007 World Cup in the West Indies because I needed knee surgery. It was a massive disappointment for me because I felt I could have added something to the team, even though they made it to the semifinals.
For the last World Cup, in India in 2011, I never really got going and came home early after pulling a quad muscle and had to watch another semifinal loss from my couch.
Now 35, this will be my last World Cup. It's been a big motivational factor for me over the past couple of years, particularly as it's at home, and those doubts and frustrations resurfaced when I strained my groin three months ago against Pakistan and had to return from the UAE.
