In 2004 I quit an extremely well paying corporate job with a nice future to get a Phd. Within 1.5 years I knew it was a terribly wrong decision. In 2006 I went back to the corporate world but haven't been able to get back on track. 6 years later I'm making much less money with much less responsibility with a much dimmer future than when I left in 2004. Woe is me.
