Surfing through my feed reader this morning, I came across a post from Kareem Mayan about why he left a job at Fox Interactive Media (the News Corp. unit that controls MySpace). The bottom line — at least from my reading of his post — is that while he got to do some interesting things at the company, he just didn’t feel challenged or motivated.

Kareem, who I met at last year’s mesh conference and is originally from Toronto, is a smart young guy who I’m sure lots of companies would jump at hiring. But he left to run a small startup that is working on something in the field of education. Why? Here’s what he says:

“After too many days of being miserable, I realized it was because I wasn’t happy with my job. I was earning a lot of money, had just gotten a promotion, lived in a beautiful apartment near the beach with my rad girlfriend, but none of it was floating my boat.”

If you’re a big company like FIM or News Corp., you need people like Kareem — but you are destined to lose them because doing something challenging and meaningful means more than having a big job with a fancy title and a nice raise or a corner office.

Just one thing, Kareem: Can I have your beautiful apartment near the beach? :-)
