I have! and... it took me 9 months and 3 IMO's to learn what I am going to tell you now... Drive to the West Coast or work Central Florida if you want to make it... Any Rural Area will do just fine...
People in the city Keep their Doors locked, hide from Cold Knockers and will tell you to get off the property without giving you a chance... On the other hand... In Fort Myers/Naples, Etc..., I have had people Invite me in before I even got up the Driveway and got to open my mouth...
I would say that is true depending on what your main focus is. If you are selling Advantage plans and Med Sups, you can do very well in that county and that will open the door for other products. I think if you focus just on Life it may not work, but it could. North FL is also a great market.
