I hear where you are coming from, but disagree in the outcome. In college, I worked in a bicycle shop. I started the job fresh out of high school and loved every minute of it for ~5 years. At that point, I was in the same position as you - there wasn't really anything more for me to learn, hated my stupid co-workers, hated the customers who didn't know or care how to change a freaking flat tire.
Meanwhile, I got my mechanical engineering degree - I loved to tinker with mechanical stuff. In the mid '80's, there were no jobs around (much like now) but finally found the one I've been at for 25 years and loved every minute of it.
Per your previous posts:
1. DO NOT do a job you don't love (or at least like.) If you're only spending 8 hours a day there, figure it out - it's 1/3 of your life being miserable. Unacceptable.
2. "What color is your Parachute" is a good book (I've read several editions), but only if you don't know what you want to do, what you are passionate about.
To the OP, a four year degree can open doors, but it's not all it's cracked up to be. We've got guys with associate degrees and some who have none at all as managers and other people who are making decent dollars. My advice is to find a company to work for who treats people with respect. The guy who founded our company used to work at Texas Instruments when it was a powerhouse in the 1960's. They chewed through EE's like they were coke on Whitney Houston's bedside table. They failed to see their inventiveness and probably blew off billions of dollars on people who left, forged out on their own, and really bettered the world. (sorry, I could go on for days)
