The advice I give to anyone who asks me this question remains the same: If all your life you have dreamed of becoming a pilot, by all means pursue it and make the most of it. On the other hand, if you are just looking for a career and flying seems like an "ok" thing, then I strongly steer them away.
My biggest reason: There are ZERO other careers where if you get fired or your company goes bankrupt, or whatever, you start back at the BOTTOM all over again. Most americans I talk to don't understand this. They think a captain is a captain is a captain...if NWA goes under, they just slide over to DAL to be a captain there. I personally know too many pilots who have started over at multiple carriers, it's no way to live----unless you absolutely have to fly.
