Jansen told the Lancashire Evening Telegraph: "I've got options but, at the moment, there are no immediate plans to get back into football.
"Everybody pretty much knows my history. I just didn't feel comfortable not being as good as I was.
"I signed a contract with Bolton and they offered me another one.
"But I thought I wasn't doing myself justice, so I ended up opting out and having some time away.
"You need the desire and the hunger to succeed, whereas I was getting up in the morning and not enjoying going to work.
"With a break - however long - I might get that hunger back and have itchy feet again, so who knows.
"That's why I'm keeping myself reasonably fit. I know I can't leave it too long, but we'll see what happens.
"At the moment, I'm enjoying time with my family. Bringing up kids is a lot harder work than you think - and so is getting nagged by the wife!"
