You get to a stage where you replay every scenario in your head, but you have to stop; otherwise, you drive yourself insane.
I'm happy staying in the World Cup bubble with England and eliminating the distractions. Besides, I want to enjoy every minute of this unique experience, and I don't want to look back and think that I was just sat on my phone.
Being vice-captain at Chelsea, I've learned to manage my emotions better this season and have matured massively, but part of that is embracing those feelings of disappointment rather than suppressing them and pretending everything is OK.
Football is my priority. It's a short career, and you have to make the most of it, which is why making the World Cup squad is such a big deal and something I will never take for granted.
What makes me so strong in the tackle? My grandad has always said if you're going in for a ball, you go 100% and you never go in half-hearted.
Like many of us in the England squad, I wasn't even born when the men's team played Cameroon in the quarter-finals of the 1990 World Cup, so I couldn't tell you much about that game.
