Lessons are the best way to start. Lessons can come from a professional instructor, or surfing family members or experienced surfing friends. You have to learn surf etiquette (so the experienced surfers in the line up don't want to drown you), how to paddle and take off on a wave, and how to ride a wave. The last thing experienced surfers want is for inexperienced people to just grab a board, rush into the surf and get in our way. Lessons shorten the learning curve significantly. And they help keep ignorant, un-prepared kooks out of the water and out of the way of more experienced surfers.
You wouldn't ask how to ride a bicycle on the internet. What makes you think you can learn surfing on the internet? You need lessons from someone who can get you started. And, two times surfing is no way to judge how weak or strong you are. Lessons and practice, and if you still want to you will have no trouble surfing. I have been surfing for over 43 years, and I it has been a lifetime of fun. take the time to learn the right way, and it can be a lifetime of fun for you also.
