How to keep your cool

For those who’ve found their zen on the course, how do you keep your cool?

I just had a round where I couldn’t find my swing at all. Halfway through I didn’t even want to play anymore because well… I couldn’t play. Every tee shot was a lost ball in the water, in the woods. I was thinning and fatting approach shots… nothing was going right and I felt like I wasn’t playing golf just pushing a ball forward 50 yards at a time.

I didn’t throw any clubs or anything but definitely threw a ball into the water with some cursing and complaining.

My main issue is I don’t want to bring the rest of the group down but it’s hard for me to not get frustrated.

Any tips?
