how would you help a person to choose an occupation?
stonemetal: >hates his job and wants to change his lifeLast time I checked there was a difference between your job and your life.  If he hates his job then fine he can change that but if he hates his life(which I would assume since he wants to change it) then changing jobs is lip stick on a pig.  Perhaps he just needs a new hobby?>The problem is, he does not really know what could that be and feels completely lost.Well when completely lost the first thing to do is stop moving and figure out where you are.  Put together a list of skills everything from tying his shoes to painting the mona lisa(and perhaps rate them from good to bad).  Figure out how he feels about the skills he does have. Use these to determine things he finds interesting.  Now attempt to do these things in a non commited  manner but with an eye towards doing it professionally(don't play video games and then say I am going to be a game developer).  Be wary of new car smell(something seems good because it is new and exciting.)  Talk to people who actually do it about their experiences.  From here make larger investments in the field: training, credentials needed etc.
