My answer is probably. FWIW, I'm 1.5 years out of grad school, fully licensed, and in a relatively good job. I think in my last years of grad school, my answers would sound ALOT like sunshine008 though. A few years ago, totally not worth it. Now that I'm done, yeah, I dig it.
But... when I compare where I'm at versus my friends who didnt go after PhD's, and instead got a job, and that job paid for a masters, etc... sometimes I wonder. There's part of me that wonders if I was a computer programmer, data analyst, etc, what my job satisfaction, savings, debt, and outlook on life would be like. Hard to really know, tbh.
All I can really say is that for the most part, I really enjoy a) being a psychologist, and b) being done with grad school.
