I would never recommend you to learn by yourself. Find a good instructor (one with good recommendations)!! Some instructors (even IKO) can be very bad. So find yourself a good one.
If no-one can stop you and you decide to learn on your own anyway, there are some things you need to take really serious, so you wont hurt yourself or more important, others..
1. Get a trainer kite and pratice for a long time with that. You needto be able to control it with one hand and all sorts of loops and circles with one hand and without looking at the kite. If you can do that, it'll be easier to control a large kite. Practising with a small kite gives you good kite control.
2. Learn all the safety "rules", rules-of-way, safty feature etc... For safety you can tjeck out my website - BeginnerKite.com (it's not finished yet, but there is alot of info on it anyway)
3. Know your gear!! Pratice with the quick release system a 1000 times on land. Get somone to hold the lines and try to release the QR in different ways. Ex jump aournd with your eyes closed and try to release. Have your friend drag you around and then try to release. It's SO imprtant to know your QR. The only way to fully know your QR is to try it in the water, when being dragged by the kite. So this is one of the first things you need to do, when you've learned to bodydrag
3. Tjeck out a lot of
instructional videos, especially launching and how to get a kite down. Most accidents happen on land (especially when launching)!! So launch the kite far out in the water, away from other kiters, so you wont hurt anybody. Ask an experienced kiter to help you launch the kite out in the water.
4. When you've got the kite in the air, you need go ahead slowly
. Learn how to move the kite slowly from side to side. Move the ktie all the way out to the side and place the kite on the water on its tips. Get it back up and over on the other side. And when you can do this easely, you're ready to bodydrag. Tjeck videos again
5. When you can do this, it's time to learn how to do a self-rescue. Whatch out for the lines!! Never wrap then around your fingers or anything else. It'll cut them right of or peel the flesh to the bone
6. And now your're ready to try getting on the board. Again, you'll need to watch videos again. Personally I like progression from fat sand. But you can find many good vids on the web too. But also many crappy...
7. After leraning on your own, you probably wish you just got the damn course... It's much easier if you find a good instructor...
And remember! It's not only yourself you're putting in danger by learning on your own. Also all other people on the beach that you can hurt
. So in case you missed my advice. Safety first, get a course...
Good luck whatever you decide
