If you don't have a passion for what you are doing it is just another job. I made good money for years in large group (100 - 3000 lives) but eventually that market changed dramatically for me and I lost interest. My focus now is working with individuals and entrepreneurs offering mostly individual major med and, when it fits, small group.
Large group, now that is where I would like to be, once my agency is sufficiently large for me to spend the necessary $$ to do it aggressively.
I dream of the day that I am wheeling and dealing in that market with a blonde assistant named Trixie that prepares the meeting syllabus and flits around the room while me and the big guys talk shop.
