Enjoy training...
Diving is about experience. In order to fully appreciate your diving you should come prepared. Regardless if you plan a 60 foot reef dive in calm and nice conditions or a long and deep wreck dive, you should make sure you have proper training from a recognized agency.
Accidents in diving are often a result of a diver panicking. Panic is often a result of an unprepared diver. One of the best ways to prepare for all possibilities that can happen, you should take a course. Often interesting, always useful and very often fun. Regardless if you want to do drysuit diving, underwater photography or a closed circuit rebreather course, talk to your dive center. They will help you become a safe, prepared and competent diver.
