Why do we work?

Law.com has a well-written piece here from Attorney Greg A. Gallopoulos from Jenner & Block addressing the above referenced question. It's a good read. His perspective is that of a managing partner at a large law firm providing advice regarding the motives of current and potential employees.

As I read the piece I thought that a lot of the factors which he suggested were the vocational motives of law firm attorneys might also be motives that motivate people to go solo.
