Actually I am fully aware of the economics of running a business. I ran a law practice for several years, and had to cover overhead, and payroll, etc.
By the way the name of the big name school was the University of Oklahoma College of Law. Perhaps you have heard of them? I hear they once won a few national championships in sports or something, and have one the best business school in the nation. But, that's just what I hear. JERK!
So....you failed at private practice. You then got a state job as a prosecutor and failed at that and now you are in teaching? Children?
Huh? Is this what teaching attracts?
Well, I hope you don't fail at this, since the children are required by law to be in your classroom. If they don't show up armed police will soon be looking for them. ( Real bullets in those guns on the hip)
