Ok. Now that is something I can work with.
As I understand it, Lottie, you want to be one of the few divers that ever earn Divemaster rating in this industry; even fewer still are the number of Divemasters that want to work professionally.

The next part is simple: there are people right now, that aren't even thinking about being certified yet, who's lives will be in YOUR hands when you lead them on a dive in a few years and something goes amiss...
(Let's not even bring up liability or Insurance)

Want more motivation than that?
