I, like some previous posters, love diving as much as for the experience itself as the things I get to see. I might be a full time dive guide/instructor but it is all purely recreational. I have no real interest in technical diving beyond the theory, I'm not that fussed by the GUE brigade - I like being able to hover upside down and spin around in the sand on my head and roll like an aeroplane and feel free from the effects of gravity.
I work in tropical resort resort locations, so I see loads of great things in pretty easy conditions, (with some pretty hairy exceptions, it has to be said) and I love the colour and the light and watching fish living their lives and the way the whole ecosystem interacts. LOOK at what you see, don't just watch it.
I share all the other reasons given above - it's tranquil, I can't hear the phone ringing or the taxi drivers beeping incessantly. All the noise is taken out of life and all that is left is your breathing and your bubbles, the booming of the breakers, and, unfortunately, noisy dive boats. It's a huge stress reliever and whatever is going on in my life at the time, I can find peace underwater.
Of course diving has also given me a certain lifestyle which, okay, is not going to make me rich and is not to everybody's taste but it suits me and my personality perfectly. I get to educate and entertain at the same time, people think I am the coolest guy on the planet, which, even if not true, is actually a pretty cool feeling, and I have to use my grey matter a great deal, which is something I enjoy doing. Good for the Mind, Good for the Ego, Great for the Soul.
Safe Diving,
C.
