I agree that each of us is on a path all our own and so that the learning should stem from what we believe we need to learn. But for every one student that I’ve had who has known what they want I’ve had ten more who didn’t have a clue. How would we treat these people? A personality test perhaps? Examining their interests?
I agree with Nitro on the point that everyone is an individual, with different needs and desires. I feel, however, that we are looking more at an age issue than a spiritual issue. Most Jedi or those aspiring to be one, are young, probably teenagers. From my own teenage experiences, I know how hard it is to understand your purpose. Once I got to my 20’s, things started to look clearer, and only recently did I really know what I needed to do with my life.
I think if you want to help these people that don’t know what they want, they need individual attention, specific assistance for their specific lives. There is no one answer.
