"But now I know the probability of that happening is just very slim.. and then I have to ask myself, is this life worth it? Do I love flying enough to work 15 hour days, earning 3000 a month for the rest of my life?"

Maybe you should get out, then. There are about 13,000 pilots between SWA, FEDEX, and UPS. Retirements will come up one day and somebody will get my job. Tough times, like we see today, and have seen before, weed out those who don't feel it's worth sticking with. It's no big thing if you decide to walk. There will be others who find the career worth while and will be happy with it.

Skyhigh was right. Not everyone is meant for the career.
