My first day in professional school we received a lecture from a Dr. in a surgical specialty. He flat out told us that if we were entering that profession to make a lot of money that there were a lot of easier ways to make a lot more money than this.
I couldn't think of any so I stayed and studied my ass off. Hope it wasn't all for the wrong reasons. I did a lot of patient care for the indigent with little or no compensation. The Good Lord did bless me however and I have a comfortable retirement having practiced the same specialty as the doctor that gave us that first lecture.
