The only surfing instruction available to us was watching other guys in the water, copying what they where doing, and hanging on for grim death if it all came unstuck, which it usually did. You re never too old to learn to surf.
Don't under estimate the kids who are most likely 8 year old to mid teens, its amazing how young these kids start surfing waves. Unless you choose the right equipment to match your level you are just adding to the difficulty. Perfect for the person who likes the feel of a longboard but wants more maneuverability.
Among the most popular boards in the water and for good reason, easy to start on and always fun. Same goes for finding your gear, the Internet can save you money and also let you compare the different available equipment. Stretch your neck, put your chin near the deck of your surfboard, and hurl your every thought and inspiration down the face of the wave as you paddle.
Non-surfing activities are also great for fitness which will always help your surfing. You can learn to stand on a board and catch a small wave in a day, or work on form, style and ocean awareness with surfing legends over the space of several days to a week or more.
