I know what I am doing....(really)
I have never been in management. I don't think I have missed anything, and I have no desire to ever be in management.
Wait, I remember the first job I had in college, I was a manager. I started working for a phone solicitation company trying to sell tickets for some country and western benefit show for the fraternal order of police. The place was located in this boiler room of a shack on what looked like a vacant lot. I was barely 18, but was very serious and looked mature. Long story short, really hated the job, my boss was a weasel. I had mostly idiots for employees. Three weeks into it, I quit and went to work at Wendy's. Then I was questioned by an investigative TV reporter soon afterward about a police report of possible fraud by my former employer.
When I was a manager, I thought you had to know what you were doing in order to be charge, and since I did not, I felt I could not be a manager.
As I grew older, I started noticing all around me that all of the bosses did not meet the qualifications I thought that managers had to have. They did not always know what they were doing, they always made bad decisions, would'nt listen to anybody, and were as dumb as a box of rocks. Then it hit me, most people in charge of things don't know what they are doing. Most people bullshit their way through work and are pleasantly surprised when things go right, and try to find excuses or someone else to blame when things don't go right. There are alot of Dilbert's "PHB" (pointy haired bosses) out there.
This may sound like extreme cynicism to you, but this was the first paradigm that finally made the working world make sense to me. Work is not always about working hard and doing your best, it's about faking your way through the day, acting like you know what your are doing and getting along with your boss and coworkers. Sure, you need to produce an acceptable amount of actual work, but getting along with people and acting like you know what you are doing is more important in the end.
