Now I don't know whether to keep it for myself and give it a go, or fluff it out and expand into a WSO or Clickbank product

What would you do? If I go the wso or clickbank method I would need to find a more experienced partner as I wouldn't really know how to market it very well, but how do you go about sharing the method and brainstorming ideas without them running off into the sunset with it?
And it could just be a load of old unworkable junk anyway, so is it best to try it out myself?
shheeeesh I dunno...HELP!
