PPf#1 Sounds like you are getting hyped up over another persons perspective. I enjoy flying, and am doing the commercials so I can get paid to do something I enjoy, more concerned with enjoying work than living a life of misery, even if it will be a long slog. If some people do for the enjoyment, they may not consider it as working as they would possibly do it as a hobby otherwise if they could afford to, I know I would - but then I guess I am young and foolish.
Most of the guys and gals in the industry started because it is something that they always wanted to do and enjoy it, not because they thought that they would get rich from it.
In terms of the robbos and schwiezers, can't comment on the schwizers, but the robbos have the teetering cyclic, so dual is no isue, but it is an expensive career change, so costs you should take into deep consideration.
