grow up?

Registration is coming up and I find myself be bombarded with the question " what do you want to be?" In the past my answers have ranged from doctor, EMT, psychologist, teacher, writer, or rich person. I am a freshman in college now and have narrowed my answer between writer and something with psychology. After hearing Liz Funk talk today I thought it was very helpful and inspiring to my dream of being an accomplished writer. She gave great advice to us on how to get started and where to look for help. However, I also took note to the fact that being a writer is very difficult way to make a living, especially since it's a warning that it's often given to me. Which is where my interest in psychology comes in. I think the mind is fascinating, I love how it is so abstract and yet still concrete and powerful. It reminds me of poetry. The problem is though, now, is choosing which one I should put first. Writing is such a big part of me so it would be a shame to push it to the side, but I need to be able to make a life for myself and I want to help people. I never really put much thought into the question of what I wanted to be when I grew up but I always had an answer. It's weird, and somewhat scary, having to truly face the inquiry and not having an answer at the tip of my tongue.
