Pickford made history when he made his tournament debut in the 2-1 win over Tunisia on Monday night as he became England's youngest ever World Cup goalkeeper while he was also the first custodian to play for England in the competition while with the Blues.
He told evertonfc.com: “I moved away from home to join Everton so it was a big change, but a good change.
“I have really enjoyed moving to the area and that was a bit of a worry – not the football side of things – but moving away from home and leaving mates. It has been beneficial for me.
“Everything happens for a reason and it is all about keeping level-headed. Every game you play, the more mature you become and, moving from home, you have to be mature and be yourself. I think it all helps make you more rounded as a person.
“On the pitch, for me, it's now about getting more games and more maturity – it's about game management.
“I am 24 and I've played 200 games in various leagues. But, for example, I can't always do long kicks if the lads need a breather. It's things like that so I'll be training hard and that's what I'll be focusing on."
