For the past 19 years I have worked in higher education. The vast majority of that time has been spent advising students and alumni on how to decide on career paths and then formulate a plan to follow that path.
One of the interesting things about the adventure that I'm on is whether I can take my own advice. Let me begin by saying that right now I am not entirely sure what I want to do. One piece of advice that I share with students is that what we are going through is a process; we won't wake up one morning and the light will suddenly go on. Instead this is a research project and it involves learning about things that interest me, things I'm good at, and things that I value - those things should be work-related in this case.
Over time, I will be doing a lot of reading and researching in areas related to careers, human resources, recruiting and such. I will be getting feedback from a lot of people with whom I've worked over time. That seems like a pretty good way to start the process. Hopefully, I will remember to compare what I learn, and the feedback I receive to what I know about my interests, skills, and values.
