I will get a little nervous when playing with others for the first couple of holes. I get this way even when I simrace online but will steady down after a couple of laps.
I think it's a natural reaction with the nerves because I don't want to make a complete a$$ out of myself on the course and will feel a little nerve even when playing with family; a couple of my nephews are MUCH more advanced players than me (also 30 years younger), having grown up in a time when this game has been popular in my area as where when I was their age I had never heard of disc golfing. They have helped my game out tremendously though, teaching me about the different discs, their characteristics, proper throwing technique, lines etc., as will anybody I play a round with if they are much more advanced than me. If it is a person I just met on the out on the course and they want to do a few holes together I just tell them that I am old and my body is worn and I just started playing the game
Seriously, when I play with one person in particular, who is twice the player I am, I just try to stay within 1 stroke of him per hole, even getting a couple of tied holes and once in a while winning a hole. No one has ever laughed (out loud anyway) at my playing and if there is any laughing out there it's just when playing with family and we'll get a little laugh now and then whenever one of us makes a really bad throw. I've seen enough advanced players make bad throws, miss some easy putts, etc. out on the course so I never feel too bad about my own ability. Besides, I am too addicted and get too much enjoyment out of playing to worry much about winning a round. I just love to get out and do it! Now if only some decent weather would just come along so I can get out and play a new course that just opened about 10 minutes away from my home....
Disc golf seems to be played by a different class of peeps compared to some other sports. No one is there to belittle your talent (or lack thereof) when playing, or trying to psyche you out or whatever and are just out to have fun themselves. It gets competitive at times, but in a good way. So far as tournament play goes, I can't say as that is not my venue. If I ever entered a tournament my knees would probably be shaking due to nerves and I'd probably hit the first tree or OB I encountered
