Jewell said: "I just couldn't stand the politics and all the nonsense that goes with the England job.
"And it's not good for your family. I am a very private man, and there is a lot of baggage that goes with it.
"I like working with the players in training. I don't do meetings.
"If we have a meeting at Wigan, they don't last longer than five minutes.
"I've no time for the old school tie and all that nonsense.
"I am what I am. I'm outspoken. The England job wouldn't be for me.
"I suppose some people think they can put on a collar and tie and it would make them come over better. But that's not my style."
Jewell's Wigan wonders have set the Premier League alight this season, winning six games on the spin, and Latics also boast the league's best defensive record.
And while Jewell landed his second Premiership manager of the month prize of the season this week, the straight-talking Wigan boss is taking nothing for granted.
"We are doing okay, and while we are flavour of the month right now, I know it can change very quickly.
"People are saying nice things about us, but it's tomorrow's fish and chip paper.
"We've now got a run of five fixtures coming up – against Arsenal, Spurs, Liverpool, Chelsea and Manchester United – where we might not get a point.
"Or we may get 15. You never know in this game."
The Wigan manager added: "Just look what happened to George Burley at Ipswich.
"Ipswich finished fifth in their first season in the Premiership – then on the last day of the next season they go down and George gets fired.
"Manager of the year, then he's sacked.
"Managers are coveted one week, attacked the next.
"David Moyes had his ability questioned, even Sir Alex Ferguson.
"So you never get comfortable in this game.
"Be happy, but never be satisfied – that's my motto.
"But if I get the sack tomorrow I'd say I've made a success of the Wigan job.
Nobody thought we'd do what we've done." Wigan host Arsenal at the JJB Stadium on Saturday with Latics aiming for their ninth Premier League victory of a remarkable campaign.
Jewell added: "I think people look at me and think 'he's a Scouser, he's quite witty, he's this, he's that'.
"But I'm really quite good at my job, you know, I'm thorough.
"People say Wigan have brought a breath of fresh air to the Premiership, that we play without fear, and I'm deeply proud of that.
"A lot of preparation goes into every game. We are very meticulous.
"And people go on about me being young. I don't think young equals incompetent.
"Look at Alan Pardew and Mark Hughes.
"There are a lot of good young managers.
"Of course I'm ambitious. I don't want to be an underdog all my life.
"But I'm proud to be from Liverpool. The thing is you don't see many people with Scouse accents getting the top jobs in this country."
