He continues to play in France's Top 14 having signed a one-year extension with Toulon but is eyeing a move into coaching when he hangs up his illustrious boots for good.
"I have spent my entire life testing ways of how to get better so I am at a stage now when I get as much pleasure from trying to get that result from other people," Wilkinson told the Daily Telegraph.
"It fascinates me. I am keen to work with players from a kicking and passing perspective. If they want to work and they are keen, I will go as far as they want to take it and as long as they want.
"I feel it is my duty now. I have spent that much time thinking about it and investing the effort and now I have got to try to pass that on."
Three of Wilkinson's former England team-mates - Graham Rowntree, Andy Farrell and Mike Catt already form part of Stuart Lancaster's backroom staff and Wilkinson admits he has ambitions to join the international ranks.
"It doesn't matter what sport you are in or what echelon of sport, the top level is what you aspire to," said Wilkinson.
"I like to work with people who want to get better more than anything else. Once you have that, you can start to create major differences.
"The important thing is that it is a start point [for me]. I still want to get better myself but also pass it on to people who want to do the same.
"I see young players who have levels of ability that I never had at that stage and it is great to think what they could do with it for English rugby," added Wilkinson.
"I am finding out a lot about myself and where I am going from my journey with Toulon and what my role is each year and the team around me. I want to keep getting better and at the moment that is playing rugby and also helping guys out where I can."
