Hello CrystalSteph: You mentioned you may be over-thinking this. And that is possible. But, I want to congratulate you for giving your choice of careers so much thought. There is a sense in which one's choice of career is the biggest single decision one will ever make. It could, perhaps, be argued that the choice of a life partner is the most important one. But, either way, one's choice of career is right up there too.
I'm an older person at this point & no longer working. But, when I was young, I never really gave my choice of career much thought. One thing just lead to another & I ended up someplace I never would have imagined. If I had it to do over again, I'd wish to be more thoughtful, as you are being.
I do think it's important to look at what the demand is going to be for a particular career. Even though you may love doing a particular type of work, if the opportunities are limited, this may not be a good choice.
One caution I would offer is, try to select an educational path that actually qualifies you to do something in particular. In other words, don't just pursue a psychology or sociology degree, unless you plan to go on to get an advanced degree & become licensed. Back when I was in school, everyone said: just get a college education & you'll be set for life... So allot of us didn't really think too much about what it was we would actually do once we graduated. And, as a result, we came out of school not qualified to do much of anything. I still see this occurring too often today.
Best wishes... you're on the right track!
