What a fantastic, funny and spot on post by SilverandSore, one that I would vote for post of the day.
The only difference I would add is a different perspective on getting to a flying career. I did mine in the military. They paid for my training and paid me at the same time. It's a great way to learn how to fly, but it's EXTREMELY competitive to get in these days, not like it was when I was accepted to pilot training.
Either way, an airline career is a great career, I couldn't imagine myself doing anything else.
Best of luck in what you decide young man, the smartest thing your doing is gathering information and trying to make decisions at such a young age. Most young adults do not do this and drift aimlessly. I applaud you.
