Yo. 26 year old female here and I've spent the past 8 years trying to validate my existence by chasing a STEM field. To backtrack, when I finished high school I was very involved in art/writing, but I started college with a pre-med and studio art major. By the time I graduated, I had a biochemistry degree and was convinced that was the only way to go. I've now 3 years deep into my web development career and I've only just begun to embrace it. Not to mention I've given heavy consideration to other things like working in policy and opening up a coffee shop.
Basically what I'm trying to say is that the idea of a chosen career path is totally irrelevant as long as you're chasing something. No matter what you do, give it your best and you'll start to realize whether something is actually for you or not. If I were to stay on the same path that I'd envisioned for myself 8 years ago, I'd currently be working 80 hour weeks and $200k in debt, but I also would have been able to call myself doctor.
I still feel this way a lot. There is too much interesting shit in the world and not enough time to pursue it all. Indecisiveness can be crippling but you just have to remember to just keep swimming. There's nothing wrong about following the path of premed -> med -> doctor, but there's equally nothing wrong about following the path of premed -> med -> comic -> actor (Ken Jeong, anyone)? You change, your interests change, and you shouldn't feel pressured to lock yourself into one particular career path when in reality, your career is NOT what defines you.
I know this is already a wall of text, but one more thing - despite being a web developer, I'm ultimately in a creative field. I am employed because I can do something technically, but I am succeeding because I can go beyond technical requirements and deliver a vision. The idea of STEM being non-creative is untrue and people shouldn't limit themselves to the idea of left brain vs. right brain. And if you are good at writing - that in itself will get you so far. Some people are straight up terrible at communication, nyeahmean?
