My head has just been all about wanting to play regular football in the Premier League.
The main reason I have joined Everton is not to try to help my England ambitions - that will come if I am playing consistently well for Everton.
Defensive midfield can be the one position that's easier to play as you get older.
You don't see too many attacking flair players continuing until their mid-30s at a high level.
When you play a lot of games in a row, and you come off the pitch thinking, 'I can't do this no more,' then it is time to look at something else, whether you have six months left on your contract or four years.
For a young player, it's important to have people around you other than yourself. You're immature as an 18- or 19-year-old.
The pressures on younger players now are greater. You've just got to be on your toes all the time with social media and stuff. Now you just go to fill your car up, and there will be somebody wanting to film you trying to do something silly like that.
If you go into a shopping centre, there are phones and cameras everywhere, and if you're doing the wrong thing, ultimately you're going to get found out. So it's important you're living your life right, and that's hard for a young player.
That's one thing that's been aimed at me since I was 17: a lack of pace.
At the World Cup, it's the very top level. It's going to be tougher.
