Dangerous
Hi all!
I think you are on dangerous waters if you try to decide for someone else what to do. You can get a lot of crap later in life from him. You don't know if he will suceed or not.
The only thing you can do is neutrally describe the situation and then let him/her decide. If there are something they still want to do, then I think that person need to be able to go for it. Then I think you would encourage that person and help whatever you can even what your own toughts are.
My suggestions.
