Breeman saidthat's simple. go with what you really want to do.. what make you the happiest? that's what you go with.
I totally agree with this, follow your heart.
To the OP, I relate to your post because my 2 greatest interests were aviation and acting. I decided to go the airline route in my early 20s but after 25 years in that business I have been thinking alot lately of how differently things might be now if I had gone the acting route . 8 years ago I started taking acting classes, eventually got professonal headshots done and do acting on the side from my day job. But if I could act full time and make a living from it, I would do it in a heartbeat!
