I'm with you, HappyDrgn. I went to Uni for three years, but didn't graduate. This was because I went for a job where 150 of us sat an aptitude test. After the results came out, I reckon they wouldn't have cared if the top 20 of us were in the prison system.
I'm a pure techo, and Uni didn't teach me anything new about computers, although I use the higher maths that I learned every day.
Having said this, I reckon I'd be a pretty crap manager, and a few extra courses might have smoothed off some of the rough edges, but hearding sheep has never really appealed to me.
There are people in my field (performance engineer) that I respect for their higher learning, usually in the statistices field where the sort of discipline required can only come from Uni, although I personally wouldn't spend the extra four years to get to that level.
