Leon Osman believes Everton's mix of high-quality football and mental strength has been the key to their impressive Premier League start.
David Moyes' side have climbed to second place after winning four of their opening six matches.
Midfielder Osman scored in the latest of those victories, as Southampton were beaten 3-1 at Goodison Park on Saturday.
And the 31-year-old argues that, in winning that match, Moyes' men displayed all of the characteristics they need to succeed.
Everton had to show character to fight back from 1-0 down, then rallied score three first-half goals, before demonstrating discipline to see the game out in a tighter second 45 minutes.
"We're playing some decent football at the minute and hopefully the fans are enjoying it - we're enjoying playing it," Osman told the Liverpool Echo.
"We don't want to get carried away. Things can change so easily in the Premier League and you saw in the second half (against Southampton) that it wasn't as easy on the eye as in the first but we had to grind it out and we did that.
"I'm not sure what the key is to maintaining it. I'm sure the manager is trying to figure it out too but we have just got to keep believing in ourselves and stay confident.
"We showed good character on Saturday. The lads didn't panic or get nervous and change the way we played even though we conceded that early goal. We carried on going and were rewarded with the goals before half-time."
Everton will look to maintain their good league start with a victory at Wigan on Saturday, their last match before a two-week international break.
Osman added: "Wigan isn't too far away we usually fill all of our end and have a few pockets of our supporters in the home end too.
"I'm sure we'll get a good following and hopefully we can carry on playing the way we have been."
