It's a massive difference when you play in front of full stadiums; you can sense the buzz around the players, and it helps us get that extra one or two per cent that may be the difference in games.
No one can complain about earning good money, but for me, it's being able to help my family out, put my brother and sister through school, take my family on holiday. That's where I get the biggest buzz, not buying a pair of £500 shoes.
I asked my daughter when she was 16, What's the buzz on the street with the kids? She's going, to be honest, Dad, most of my friends aren't into Kiss. But they've all been told that it's the greatest show on Earth.
I like to write in coffee shops in countries in which languages I do not speak are spoken. That way, you're surrounded by the buzz of humanity, but you aren't distracted by people's conversations.
If you remember back to some of the television we saw, Buzz and Neil on the Moon with Apollo 11. Black and white. They were bouncing around a lot. They were really bouncing on their tip toes. Quite fun to do.
When I finished playing, I didn't think I would be able to replace the buzz you feel at kick-off, but when the light on top of the camera turns red, and you're about to go live to the nation, it is a very similar feeling.
Ever since I was nine years old and I watched Neil and Buzz walk on the moon, I have felt passionately that this is an interesting human adventure. This is one of the things we're doing that is really fundamentally important, as we leave our home planet, but also exciting.
