Knowing any choice is great

Dear Brooke, my fiance is deciding whether or not to stay in his career or start a business (partially because he feels stuck in his job). Following some the response on this page, I asked him if he knew he would be successful whether he stays or leaves, what would he choose. He immediately chose to stay. So then he asked what to do next and I couldn’t explain it! Knowing the model, I would put it in a model to find the thought that would result in advancement in current job. Is that right? What is the bridging thought?
