Personally, I want to feel purposeful at work and that I am contributing to a better world. I also absolutely require regular challenges or I end up severely depressed. Also, I have undertaken extensive education partially as a way of raising my standard of living and having a more enjoyable life outside of work.
THERE ARE SO MANY THINGS TO DO WITH YOUR LIFE! Yea, it's not always going to be a party, but there's a hell of a lot more to it than sitting in air conditioning. And you're allowed to demand a hell of a lot out of your career as long as you are willing to put in the work to get it.
My search for a challenging and intrinsically and extrinsically rewarding career brought me to study the life sciences. Then I ended up in a healthcare company doing menial crap and then a graduate degree in bioinformatics. I'm looking through job-ad after job-ad, and while the occasional one looks challenging I am absolutely terrified that I am going to end up as a desk-monkey who doesn't interact with people and again gets no challenges.
I hope I am wrong and I can make this career work for me, but I am already looking at applying to medical school in a year if can't find a challenging and decently rewarding job in bioinfo. Sucks, because I had originally intended on being a doctor when I was in undergrad but went in another direction because I wasn't 100% sure about it at the time. Unfortunately, I am 100% sure I do not enjoy being a desk jockey.
