Currently, no. My biggest fear is investing years into something I end up hating. My 2nd biggest is what I'm doing now: drifting aimlessly. Finished University, and I have the grades for pretty much anything. I have no desire to do med-school, and the same goes for law. (SF makes it sound like a horrible place to end up anyway haha). I've been thinking about doing Business School in a few years... I'm less interested in business, but I like the concept of actually having a skill set that will let me go where I want.... unlike my current social science degree.
Those of you who managed this work/love combination... I'm entirely jealous. Was it lucky happenstance? Or did you know what you loved... and made a career from it?
