Go here and see what the US Dept. of Labor Statistics thinks your proposed occupation will do for you over the long haul. Choose a job that makes good money, shows stability for the future, has workable qualifications for entry, and has adequate projected growth in the decades ahead. You can have two careers at once, I have been doing flying and engineering for a number of years. When one goes south I just do the other one for a while. Good luck! And keep working on that grammar.
