The problem with forums is that when you ask a question on a forum, you get various answers including various opinions however, I have found that the hardest thing is getting a NON Bitter or NON Biased answer from people. Aviation is a very "Feast or Famine" business and thus the opinions regarding the industry are usually (Not all the time but a good number of the times) either "feast or famine" minded.
With that in mind...
The Truth About the Profession - Home
This page is probably the BEST overall, all inclusive, least bitter and least biased explanation of "The Truth about the Profession" that I have found out there. I explains not just the fly and the way of life but it also takes on a bunch of widely regarded rumors among pilots and the public as well. I hope it helps and good luck with your decision.
