Hey, buddy. Of course, you won't wish anyone what happened, but no shark will catch up with you at a fast speed, and even more so if it's a big wave. I have recently started doing this sport myself and on https://easy-surfshop.com/ I bought everything necessary for this. The easiest way to learn something is to try again and again, you should see improvements as long as you know what you are doing wrong. Surfing (with a longboard) is not difficult at all. Start by riding on your knee, then on one leg, then standing. In the surf shop, I bought the necessary equipment for surfing until this summer. My inventory is outdated.
