Find your happiness, then find your job
It took me less than four months of working for a major TV/Radio network in Manhattan to realize that I was headed on the wrong career path, but boy did I wish I had figured it out before taking the job.
My regret? I never took the time to really sit down and weigh all of the positives and negatives of the journalism career I was about to embark on. More importantly, I never even asked myself, "Is this going to make me happy?"
Yes, you have to work and yes, it's not always going to be fun. But it doesn't have to be miserable either. Who said you weren't suppose to enjoy what you do for a living? Plenty of people like their work. Why shouldn't you be one of them? It's true that your twenties are about "paying your dues," but shouldn't you at least pay your dues in a career path that is going to fulfill you as a person?
I learned the hard way that declaring a particular major in college doesn't mean that you are FORCED to pursue a job in that field. Prior to looking for your first job, make a list of what would truly make you happy. Even ask your family and friends for their perspective. Have they ever witnessed a passionate fire in you or an excitement in your voice? If so, what were you doing at the time.
Once you have a solid idea of what you enjoy, you're better equipped to search for a job that will allow you to fulfill your passions. Take it from someone who just changed careers and is much happier for it... before you jump into the job hunt, take the extra time to figure out what will make you happy. It will likely save you a lot of time and frustration in the long run.
