You sound young enough that you could make out either way in this business or with a new career. If you have 30 yrs left in aviation, you'll do just fine. Despite what the public and mgmt think, planes don't go anywhere without pilots. And pilots will raise the bar here again the the not-too-distant future.
That said, I feel your pain about this being a J-O-B as oppose to a passion anymore. But as far as jobs go, it's still a good one.
I left aviation once before to pursue a career in banking. I made lots of money and had a great time doing it. But I became a different person and the semantics of that industry began to grind against the character that I am (lack of ethics in banking didn't work for me). When I returned to flying, many of my peers were years beyond me. But that's ok, I had a second career to fall back on and life experience... or so I thought.
That was in the 1990s.
After 9/11, I sought to set up a safety net once more. This time I started a business that was initially very successful. But after time, working as a pilot, and as a business owner, took it's toll on myself and my family. Then came the problems of local government, employees, banks, contractors, customers, lawyers, etc. As a business owner you have one giant target painted on your back. Everyone wants a piece of what you're doing. Everyone thinks it's their constitutional right to approach you with their hand out... then with a gun in their hand to take advantage of you when you tell them to FO. Of course, it depends on the business you're in. I was in a labor-dependant, equipment-intensive one. At the end of the day, and after more than two years of mental turmoil over the thought of "giving up", I shut the business down. I have no regrets, except that I waited too loing to exit.
The point is, sometimes reality is not as clear as the idea of what you set out to do. Try your best to think through all the variables. I'm not saying business isn't a viable option. I know many pilots who are quite successful in business. But it's not the be-all, end-all some make it out to be.
I remember the very moment I made the decision to leave Wall Street and begin the uphill battle of getting back into aviation. It wasn't easy but I did it for the lifestyle rather than the bucks. Of course, the bucks are a means to afford the lifestyle. But the lifestyle is more about the enjoyment of life than actually flying jets here and there. Once I realized a side business completely encroached on my lifestyle goals, I knew it was time recognize that wearing two hats just wasn't going to work.
Life really is what you make it, man. I love to complain, vent, be negative like the next guy. As pilots we all do it. But the moment I realize I'm going too far with it, I try to take a step back and focus on the more positive aspects of my job. Once I do that my attitude tends to change. A good attitude at work makes the gig much, much easier.
I wish you well in your endevours. Believe it or not, it is noble to admit when things just aren't working out for you and effectuating a change to improve your life is the next logical step. I myself have thought about going to law-school to become a labor lawyer on the side (seems to be a real shortage of ethical ones out there). But I'm not there with my decision yet. Right now raising the little ones and just enjoying what I have is my MO for the moment.
