Welcome to the club and get comfortable, it's always packed. Here we can offer you bitter resentment, never ending regret, and green envy served chilled. Or we can offer you a reality check. Getting a job is fucking hard nowadays and there isn't anyone above this issue.
We're stuck in that weird limbo of being over educated yet under qualified for just about all jobs right out of college. Let's not even get to the legal form of modern slavery aka unpaid internships, because that's a whole different ball game. The fact of the matter is if you graduated without at least 5 years prior experience, a masters degree magically received in 4 years, or money to burn as you work that internship flow, you are going to end up at a job that has nothing to do with your degree. Accept it and realize that's actually fine.
In fact, it's more then fine! Where were you when you first chose your major? I was a freshmen, hungover as fuck, and just realized that I was pretty good at that mandatory creative writing class. BOOM welcome to the wonderful world of writing majors. I was 18, how the hell was I suppose to know what I wanted to be besides rich? I'm now 23 and still wondering what I want to be for my whole life. I regret nothing. The working years are long, whose to say you're suppose to be at that ONE dream job your whole life? Sounds like a bore to me.
In the past two years of "adult life" I have held 4 jobs and to be honest I adored 2 of them, one of which I'm currently at now! Does it have anything to do with writing ... Fuck no! In fact it's the furthest thing from writing! To be honest, I would have NEVER realized how much I loved sales if I didn't just sit back, accept that a writing career wasn't just going to fall open in my lap and embrace the bitter wonders of the job market!
So Millennials do yourself a favor and cut yourself some slack. Your degree was NOT a waste of time, you will be successful, and you will find your dream job. Just don't get so wrapped up in what you're "suppose to be doing" that you forget how awesome your first few years out of college can be! If you work hard enough, life anyways has a funny way of working out.
