No, you're not. I'm 44. ERAU grad, zero flight time. I will be starting my training this summer at a local FBO and then transfer to ATP in either ATL, DFW, JAX or STU. My plans are to get on with a regional and then evaluate where I am at the 3 yr and 5 yr levels. From that point, I'll make a decision to either stay with the company that I am with or pursue the majors (pax) or box haulers (UPS/FedEx). My wife is a school teacher w/two M.S. degrees, so I'm not worried about our earning potential.
Also, we have a 24 month old little boy and a 2/2, 2-story townhome in Ft. Pierce, FL. A lease pymt could pay the mortgage there and part of a mortgage on a new house say in NC or TN, or we could just sell it and start over.
I say go for it.
Do the research, though. Who knows, maybe one day you'll be my FO.
Best wishes & blue skies.

PS--Although I may only have 13-15 years to fly as a professional pilot, it'll be the best 15 years of my life.
