There will be first time for everything. Do you remember when you drive a car for first time? For me the feeling was same. I was nervous. My heart was beating very fast. But I told myself that it will be worth. And it turns out to be one of the best thing I ever did. If you are thinking to go diving or get a scuba diving license, my advice will be try it first. Ask a professional if you have any questions. Here in Okinawa, we can take you to the famous blue cave for your first dive.
