I'm a Marketing major, I'll be finishing my degree this coming May!
I have done about 25 dives, and I'm going to be doing about 6-8 more next week when I'm in Aruba/Curacao. I know I have to do more dives, but since I'm in school and working full-time when I'm not, it's a pain to drive up to Mich and such. I was thinking about doing the whole "schibang" at once (much likes the ones in Thailand you mentioned). Since I hate diving in colder water, I wouldn't mind instructing in a place like Thailand if thats where I would do instructor training. I actually got some free dvd in the mail that I ordered from Mermaids in Thailand, and it looks pretty cool. Does anyone know anything about this place.
Driving to Michigan is not a "pain" for those of us who love to dive! And if you don't love to dive you will not enjoy being an instructor.
Most new divers who "hate" diving in colder water simply have not dived in cold water while wearing sufficient insulation. 7 mm full suit with hooded vest and 5 mm gloves might get you there -- trying a couple dives in a drysuit will definitely expand your universe.
When you've experienced a few weeks of 25 dives per week you will have a much better idea of whether you love diving or could enjoy doing it for a living.
Go diving, dude.
