Warning in advance, this might be kinda long. I'm a senior about to graduate highschool. I love theatre more than anything, and it's one of the only things I can see myself doing (and truly loving) as a career. I'd be content working in theatre in any capacity. I don't need to be the lead in some huge production to consider myself successful, I just want a place on stage or behind the scenes (I love performing, working tech crew, writing for the stage, there's not a part of the process I don't love). I've definitely thought about majoring in theatre, but I'm not delusional. I know it would be insanely difficult to make a career out of, and that I'd basically be signing up for unstable work and bad pay for most, if not all, of my career. Sometimes I feel like I'm up for the challenge, sometimes I feel like it would be better to give up/only do community theatre as a hobby.
The only other thing that's really stuck as a potential major/career path outside of the creative world is environmental science. I wouldn't say I'm as passionate about it as I am about theatre, but I definitely have a solid interest in it and I can see myself enjoying working in that field long term. Unfortunately, while science work is arguably more stable, this career faces its own uncertainty. Budget cuts, pay, stability, all of these factors effect environmental science too.
I guess what I'm stuck on is deciding if I should pursue my dream, or the more logical interest if I'm gonna face similar challenges regardless, should I just go after what I truly want to pursue? Or is that too unrealistic, and should I try and find my footing in my plan B?
