Please put some thought into it. Do you want to become a scuba instructor because you simply love to dive? That is not a very good reason. Want to become OWSI because you simply love to teach? Again, not good enough. How about because you love to teach AND you love to dive? Getting closer. Let's say you really would love to teach others and you enjoy socializing and can't get enough interaction with other people. You really entertain the idea of going home at night and laying in bed thinking of ways you can make Mrs. Smith more comfortable in the water, of course you're doing this while repairing a reg. You welcome the thought of spending hours and hours teaching the dive planner to a bunch of Boy Scouts until you know they are comfortable with it. Ahhh yes, one more, you delight in the prospect of living on Ramen noodles cause the pay just isn't putting steak on the table (maybe every once in a while). If that truly describes you then the scuba industry has been waiting for you my friend. If there is any hesitation then pursue the degree. Heck, either way, keep diving!
