I do think humility is the watch word here. With a little more life experience the lad might realise that there are a lot of good people doing necessary jobs which he feels would be a life worse than death. I know of a lot of pilots who have had to do all sorts of things to make ends meet from washing planes and sleeping on mattresses on hangar floors to build hours and follow their ambitions.
This lad is undoubtly lucky and has supportive parents for him to be there at 19 years old. Too bad they didn't make him do a typical gap year activity between school and the next phase of his life like work in a pub and then go traveling with a backpack on. Maybe that would have given him some grounding first, so to speak.
