Pushy or passive?.......

So..... He that is the teenager has beaten nearly 300 other applicants/contenders for one of 20 positions to be apart of this amazing opportunity. This opportunity is the Comenius project. This involves varies project that will take him to 6 different countries over two years for 1 to 2 weeks at a time. I am very proud of him for getting picked even though I am very nervous about him leaving the country without me. I have embraced this as a golden opportunity for him even though it will come at some expense to myself. I feel that it can only help broaden his horizons, encourage his independence and teach him some very valuable life skills. These sort of opportunities were not the sort of thing I would of been able to participate in as funding for this sort of thing was not even an option in my house hold growing up. Not that I'm complaining, I had an amazing childhood but that's another story. So I guess getting to the point, he that is the teenager is now after a couple of months of being on this project, has lost interest and feels like he no longer wants to participate. Now the burning question is, do I try to encourage him to carry on, inspire him and kind of push him into continuing or let him make his own choices (which if he chooses to quit I believe he will regret!) and back up his decisions. Again there will be a lesson learnt, that no matter what, I will always be in his corner supporting him in his decisions? Also, validating that his opinions matter and he does have choices! Parenting is a minefield!! I wish I had all the answers!!!
