See if you can catch on with a school or shop.....like the others say, teaching anything is a whole different ball of wax.
I used to be a scuba instructor; I worked for a few different companies, one contracted to a few shops and then for a couple individual shops. I was young, 22 when I first started doing it and really had very little idea about how to teach someone how to do something that I knew how to do. Since my first job was in a company with three older instructors and me, I started off (after completing the requisite trainings, certifications, etc including several first aid and lifesaving courses as well as O2 administration, CPR and even live practice of helicopter evacuations (my first ride in a helicopter) as well as insurance which for diving in 1992 was USD 400/year.)....I started off working as a dive master, which is what I had been doing for the 6 months or so leading up to
my surfing instructor certification which I worked on after hours. I watched HOW the instructors taught with the various teaching theories swimming in my head that I'd recently learned in
my surfing instructor certification courses. The senior instructor had been doing it for 25 years or so, and not only could he keep things light and fun, he could identify the problems each person was having and would address them in a serious but not "heavy" manner until he was satisfied that they had done an acceptable job with a new skill. Already long story cut short now, even though I had 1000+ hours underwater, worked in a variety of underwater jobs and capacities as 1st mate on two research diving vessels, month long archeological dive of 8 hours daily, I was not good at getting across the basics to a stubborn learner who was not a good swimmer and/or otherwise apprehensive about the experience. I learned but at the side of seasoned professionals until I was ok to lead classes on my own.
The other thing is that if you love to surf and think that it would be fun to have a job that allowed you to surf while you earn money, think again. I loved diving, but work is work and I spent a lot more time carrying tanks to and from boats, fixing regulators, scrubbing down said boats, replacing fin straps, etc. than I did diving, and when I was out there I was constantly buzzing around checking everyone's air supplies, buoyancy control, navigating via compass and time and estimating the point of return based on the largest air consumer in the group and how to make sure that we ran thru all the skills we were working on while still having time to look at the reef/wreck or wherever we were diving and making sure that it was "fun" and that we all wound up back at the boat when the biggest air sucker was at 500psi.
Work is work; my advice is to make pizzas or something for money/your job, then surf for FUN on your own time.
