I would recommend Pilot as a vocation for anyone who wants to fly for a living. I would also suggest they look into the many avenues of pursuing flight as a career and the many diverse careers available. If their dream is to be that stiff-backed triple breasted flying god dragging a rollerboard, I would suggest they go for it and simultaneously temper their expectations and be prepared for the possibility of that not working out due to industry vagaries.
While triple breasted flying god is a great job, to spend a life wallowing in the effort to get there while not enjoying the craft of flight is a huge waste. Some folks get there quick and some folks never get there. We all need to be prepared for whatever path results from the culmination of outside forces and our own actions.
I would also recommend a year spent under airplanes with a bottle of Simple Green and a brush as a healthy way to appreciate whatever job in the cockpit one happens to land.
