I'd go back to flying. All the money in the world is not worth it if you're not doing what you love. And since you said you've wanted to do it since childhood (me too), you now have a second chance at working a job that you're passionate about.
I've known plenty of folks who have careers making a lot of money and are the most miserable SOBs I have ever talked to. Simple, they are stuck in jobs that may pay very well but it is not their passion.
I may not make what a hedge fund manager makes working here at AA, and I am a strong Unionist who fights the good fight for the best contract possible.... But I am living my dream career and still having a blast flying 737s in my 15th year.
Do it and don't look back! And enjoy the ride.
