I have an amazing friend who did most things right with her own life (sold her business and retired last year at 52, is supermom, calm, collected, the person most likely to succeed and coach her friends into success too). We were having tea one day and she said I needed a career, because being a secretary in a law office wasn't my passion, wasn't really paying the bills, and I have the ability to do more if I want to.
So we brainstormed, and she kept shooting my ideas down because they weren't lucrative enough. Not that there was anything really wrong with my choices--the world needs social workers--but I'd been barely making any money for the 10 years since my separation/divorce, and I need to play catch up on investing. So she pointed out that there are lots of helping type jobs where I could still get that emotional satisfaction and a larger paycheck, but they're in the medical field. So we looked at all types of therapy, and I decided to go into speech.
I'm going to work in schools, but I'm doing a medical internship (as well as an educational one) and I might fill in in nursing homes during summers and weekends. Who knows? I'm thinking of teaching in DoD schools because I'd get hiring preference as a veteran and some years towards retirement already squared away (not that I want to retire, but it would be nice to have the option.) I've lived in Japan and Korea before, so if I start there, I thought I might be able to do accent reduction on the side as a twist on teaching ESL--or, with my Masters, background in Korean and Japanese, and BA in English Lit, I might be able to teach a college class or something in English or accent reduction.
So that was convoluted, but I picked the career I'm working on by looking at my passions, what I'm good at, and practicality. I like it that there are so many possibilities with a speech degree (schools, early intervention, swallowing evals in hospitals, swallowing training and aphasia therapy in nursing homes, accent reduction, voice therapy on my own or in an ENT's office, working w/head injured vets etc.).

It's a great field, I think, and so far I love all my clients, even the difficult ones. Especially the difficult ones.
