Follow your passion, for sure.
I worked in the software industry for many years. It was lucrative and I enjoyed it. But one amazing night, attending my friend's homebirth, I realized my true calling: to become a midwife. My path toward that has been derailed for now (husband not thrilled by the tough lifestyle inherent in being married to someone on call, particularly while the kids are still home) but I ended up volunteering for midwives instead, and that has built into actual paying jobs that keep me involved in what I love. Doesn't get much better than that!
