The former Manchester United and England goalkeeper has revealed that he does not view football as an all-consuming passion.
Foster told the Baggies official website that life in the Midlands suits him down to the ground.
He said: "I never once regret what I've done in the past and I don't regret anything in my career everything happens for a reason.
"I'm too laid back, I don't take this football thing as a 24/7 pursuit. I love playing it, I love Saturdays but it's not the be-all and end-all.
"You learn from it and it makes you a stronger person on a football pitch. I learned that at a club like United it's very cut throat, succeed-at-all costs, you come away from it as a stronger person."
