Relax just a tad. I think you're reading too much into people's responses that aren't realy intended. It is VERY difficult to read inflection, tone, and intent from the written word, especially when people's writing styles differ so much from their in-real-life personas. My first bit of advice for you is to always give a person the benefit of the doubt when trying to interpret tone and intent. Most people are here because they want to
help others, not pick on them.
Secondly, in my personal opinion you really can't seperate "life lessons" from advice on the aviation profession. I speak from experience. I made the change about four years ago, and reduced my salary by well over 50% to do so, and have never been happier. BUT, I'm happier because of the life lessons that I've added to my repertoire, in conjunction with what I've picked up about being a professional pilot. They go hand in hand. The way that my wife and I have handled the changes are much more important in my happiness than what those changes were, you know what I mean?
As far as learning life lessons, I'm of the opinion that you should never quit. The older you get, the more that you realize that experience is a great teacher, and learning from others' experiences is a very valuable tool. Let's see, you've been an "adult" for 12 - 13 years. Kristie has been so for 20+ (almost twice as long), and I was an adult when you were born (close to three times as long). Maybe, just maybe there is something that we can add to what you've already learned. Maybe not. But if you shut us off from even offering info I can guarantee that you won't learn from our experience.
I recommend that you be careful about cherry-picking the answers that you want to hear. I can understand that you might feel defensive about people talking about issues that are not directly aviation related, but you just might be missing some valuable information along the way. At the very least you can end up with people thinking to themselves "I'm not going to bother giving this guy any advice. He won't listen anyway." I can tell you that right now I'm on that fence myself.
Please, just keep in mind that people are here to help, especially Doug and Kristie. Really.
