Angry and frustrated while surfing

Hi all,

Advice needed. I love surfing. However, over the past year, I have noticed that I easily become angry and frustrated while surfing. I love surfing alone, so often the reason is related to other surfers, crowded lineups, people not respecting the etiquette, etc. But bad waves, especially closeouts, not catching a wave, and not performing enough well ("you should already be better!") are also frustrating. When I say that I am angry or frustrated, I am not yelling at anyone or anything. I probably just look very pissed off, so it's more about my thoughts, etc. I am trying to stay positive, but sometimes it’s so hard.

Has anyone been in this situation? What can I do? I surf a lot so not being angry or frustrated would have a huge impact on my life..
