Okay so this is a strange one, I've nobody in RL to ask for advice, so I'll give you a brief back story... I'm having a bit of, what can only be described as, a quarter-life-crisis at the moment. I'm 25, I graduated from uni two years ago and have been working as a teacher since then. I enjoy my job, but I always have this niggling feeling that I will get bored of it eventually, and bored of the poor pay if I don't want to become a head teacher. But at the same time, I battle with the fact that relative to my parent and partner, it's decent and stable money (28k) and that I wouldn't be guaranteed this money if I left and did a non-teacher job. So basically I worry that if I leave i wouldn't know what to do or what I'd enjoy doing, and I would definitely have to take a pay-cut and may never out-earn what I do teaching anyway.
So to my feeling weird part... I was staying with a friend on the run-up to Christmas, who was telling us about someone who we went to uni with. We all went to a pretty low-rate uni, this person studied business there. After graduation, they were working in restaurants and bars, alongside a part time office job and applied for a job on a whim. They got the job and have ended up on 50k within a matter of months.
I can't put my finger on why it's impacted me so much, but I can't let it go. Not so much about them, but more-so about what the hell I'm doing with my life. My partner earns less than me, he's trying his best to persue promotion and we are scraping to buy a house together. I feel like I'm failing him and myself because I can't gun for a payrise/promotion in my job. I just can't let go of the fact that I could be earning 50k VS the reality check that I keep trying to give myself that it probably doesn't work that way for most people. I'm feeling like I'm failing to provide at the moment, and I'm worried that if I stick at this job I'm going to reach 30/40 and wonder what I could have done/been earning at this point. My degree is in education and psychology (regret), and so I feel like I'm pretty pigeon-holed.
I need some realistic advice because I can't let this go and I have nobody to ask who might offer helpful suggestions.
