So, I think I might want to change careers again. I'm 34, I am working as a Senior Analyst for a large engineering group making maps using lidar and GIS. It's a good job, work from home, 58k a year. Its exactly what I set out from college to do but now, more or less I'm bored. I want a master's or some other upper level degree. I've spent the last 5 years caretaking my fiancee and mom in the hospital and it has me thinking about med school. Am I crazy? I would only need about a year (6 or so classes) to technically get into med school, besides MCAT. I mean my current trajectory with my career is programming and more or less sitting behind a desk (home or office) the last 5 years has me uninspired. And programming is not hard for me to learn just, it's hard to learn if your not interested in it. I do better with more interaction maybe? Should I be a geologist? That's not far out of reach either but I've tried oil and gas and it's not really my cup of tea either. More or less I'm the only one in my family who went to college and I am rather high achieving but I don't have much direction or network. I've been care taking so a lot of my free time has been taken up by that but now that that's winding down I'm wondering what the hell I should do to not be bored/poor. I'm good with high stress, thinking on my feet and being calm, I am a logical person who is nice. I thought about being a teacher growing up but I don't have kids and it's kind of a shit job. I love travelling and unsolvable problems. I am just a little lost. Any advice?
