Mourinho spent three years at Chelsea earlier in his career and returned to Stamford Bridge in the summer because he loves the club and is excited about their long-term project.
He claims to be on his 'worst' contract since leaving the Blues in 2007, but is already looking beyond the end of his four-year deal to what he hopes will be a golden era for the club.
Mourinho would then like to experience international football and hopes to lead either home country Portugal or England into a World Cup.
"Realistically I hope at the end of those four years we sit, analyse the situation and that will be the point where we both - club and me - are happy to carry on or happy to separate," said Mourinho.
"But I would like [to stay for], say, 12 years. I'm 51 next month. I'd say 12 years, and then two to go to a World Cup with a national team. I would prefer the Portuguese national team. England second [choice], yes.
"The best way to [run a club] is to do it with stability. For the players, if you want to help them grow up, you do that much better with stability: in ideas, philosophy, model of play, style of leadership.
"This all comes from stability at the highest level: with the owners and board and, after that, the manager. The second line of the hierarchy.
"That stability is very important. You look, for example, to Manchester United and everybody feels David [Moyes] will have his time to do his work in a calm way. I think that's fantastic."
Mourinho maintains that his return to Chelsea was not financially motivated and that it would have been easier for him to go to another club.
"There were a lot of teams [offered to me] who could be successful immediately in my hands," Mourinho said.
"I had Real Madrid: I left them because I wanted to, not because they wanted me to. I had other clubs in other countries where it would be easier to go and find an 'easy' job immediately.
"If I was here for financial reasons, I wouldn't be here getting a lot less money than I had at Real Madrid, where I had three more years on my contract.
"I didn't come here because the job was easy, or because I had a team ready to attack the title, or because I was coming here for the best contract of my life. It's the worst of my last six years. I'm here because I love the club, I love the project. It's a different project."
I fear for the sanity of Abramovich ! He was advocating his desire for exciting football and yet he employs this specimen. I am lifelong Chelsea supporter and am now at the stage where I hope we embark upon a loosing streak in order that he is ejected. He turns up at Arsenal playing for a draw. I thought the objective of a football game was to win ! Watching Paint Dry springs to mind.- vivabirchenall
