I just turned 50 in August. I have had my D/M for 1 year as of last week and I am strongly considering entering the Instructor realm. I know I cannot make a living from it (in this area), but I enjoy working with the classes as a DM and love passing along my passion to those that want to learn it. As an Instructor, it will be about the same thing. It’s mostly about passing long my knowledge and bringing up the next generation of divers.
