Are you an ISTJ who enjoys your career?
What do you do? Did you enjoy the coursework that got you there?
At 29, I am a structural engineer w/ my PE. This fall I started taking night courses. I am enrolled in an accounting program but am definitely not passionate about learning how to audit or do taxes. I may be good at it, but just about any liberal arts class would be more exciting (sociology, history, psychology, heck even art or music.) Not sure what I would do with those liberal arts classes though.
