I'd say the biggest difference is knowing you can do something. You can sit here and say, 'I believe I can get a hundred tomorrow'. But it's a different statement to say, 'I know I can get a hundred tomorrow'. That's something I try to think about.
I have learned a lot of interesting things about nutrition in my cricket career but the biggest lesson of all is to ensure your healthy eating habits are sustainable. The best way to eat healthily is to think of nutrition as a lifestyle, not as a diet.
I love Japanese food - it's a really healthy way of cooking and it is very easy: I often just steam the vegetables and fish together, make a space for the noodles, and I have a great healthy meal in 15 minutes.
I have a more personal insight into the importance of core strength because my wife Louise runs a Pilates studio in London. I have enjoyed getting into Pilates. I am not the most supple but I enjoy Pilates more than yoga.
The game in T20 cricket moves so fast and guys are always putting you under pressure - you can have plans for the likes of Chris Lynn and Glenn Maxwell and try to execute them but they can then do the exact opposite of what you expect, especially Maxwell.
Although I train hard with England and Rajasthan Royals, when I am at home in London I always like to join some group fitness classes and experiment with new workout ideas.
What was scaring me was if we lost, I didn't know how I'd play cricket again. This was such a once-in-a-lifetime opportunity, a World Cup final at Lord's.
It's a privilege to be on the same field as guys like Jimmy Anderson and Stuart Broad when they catch fire like they can do. Two of the best there has ever been.
T20 in international cricket can almost be paid lip-service at times, with one game tagged on to the end of an ODI series or a long tour - sometimes it can feel like there is no point in playing it.
For me, a circuit might involve a warm-up, then one minute on the treadmill or the indoor bike followed by a series of 20-second efforts with burpees, tuck jumps, press-ups and standing rows. I might repeat that 3-4 times.
