Maybe I'm a bit late to the party to post, but I don't think money is everything. No matter what you believe in, be it re-incarnation, one life etc, you can't take money with you when you die. That doesn't mean it's a shame to chase after money, but I would put your main passion in life first and then try to make money by doing it. Maybe you won't make any serious money till your tenth year of flying, who knows? But in the meantime, enjoy the ride, love what you do, move about a bit and do whatever it takes to keep on moving up. None of us who are starting out can expect to fly a nice shiny wide-body right after "graduation". Yes there have been a few people who have done that in the past, in different countries around the globe, but that's another matter entirely. I think there is something to be learnt from having a linear progression, ie SE to ME, ME to Turboprop, to Jet etc. But I digress.
I'm in the same boat as you are, 30 years old right now and have been working the other side of the radio for the past 10 years. Flying has been my dream from day one, along the way there has been a few distractions that have kept me from flying, be it pursuit of money, marriage, wife in school etc. I'm at a stage in life where I make real good money (6 figs), and have a good retirement plan. I even work in "Aviation". In spite of all this I'm hanging up my day job and jumping full time into flying in 3 months. I have been flying for the past few years and have about 175 hours, I can fly once a week for fun and still keep my retirement and good pay if I wanted to. But at the end of the day I have to say the only thing I have been passionate about in life is flying. And I would gladly give up my current lifestyle to pursue my dreams, because at the end of our days the only thing we can look back on and take with us are our dreams and experiences, and not money. Am I about to regret it? Perhaps,perhaps not...but the biggest regret of all time would be not trying. My two cents.
