Why does golf have to be so hard?

I played golf yesterday, which is my usual golf day. I have been playing golf, off and on, since I was a teenager, and it is as hard now as it was then. I still shoot the same terrible score. I have flashes when I seem to be gaining consistency, and then all of a sudden I start playing like I am playing my first round ever. I have never worked so hard to stay so mediocre at anything in my life. But wait until next week. I think I have it figured out!
