Rae, some great advice here already !!
A couple of small suggestions. Think about volunteering somewhere in an industry that you think you might like. It gives you connections and exposure.
Coincidentally enough, I used to be in molecular biology, and since I have become a SAHM, I have done some volunteering. I found that I could NEVER be a teacher, but I really like working with at-risk youth ( like gang members ). I have, on a few occasions been asked to volunteer interpret for Catholic Charities and our local hospital, and I loved it ! Can you use your skills to interpret ? Also, good communicators are really in demand. Have you thought of learning to write grant proposals and then free lance that ? You could even start that now and see if you like it. Start small. You could put together a small proposal for a series on article on thrifting for a local paper....
I am reading a great book called " Kitchen Counter Cooking Lessons.." The author studied at the Cordon Bleu, but she writes narratives about cooking. Could you do something like that ? ( Not about cooking, but something else. )
Finally, it is ok to be all about the money for a little while. You don't have to spend it. You can save it and invest it and maybe by the time you are 50, you can stop working for pay and do something that you really love, like travel. Think long term. In the end, some times a job provides you money to fund the rest of your non-work life. And you seem to be enjoying that. Don't let your dad's ambition make you doubt yourself. ( Recently, my mom' brother, who lives in Europe, told my mom that he couldn't believe that my parents were "allowing" me to not work. He said that they had put so much into studies and that I had spent so much time studying molecular biology that it was an embarrassment to the family that I just did "nothing". I am 48, he needs to stop holding out hope, LOL !!!! Wait til he learns I like hanging out with kids who carry guns and knives ! LOL !!! It is cultural......and trust your self. One doesn't have to have a burning passion. Some of us just don't . BUT you do want to be happy !
