When I was 18-23 I was always pissed at my bow. I took a dozen years off of shooting and now I'm a lot more mature and much more educated about archery (read alot of books) Now I don't get angry, I just fix the problem with the bow or with me and get back to shooting.

I think that learning to do your own bow tuning and repairs goes a long way to learning to not get mad at your equipment. I paid for every one of my Larry Wise books in about a week of tuning and repairs.

The last two years of shooting, and especially the last 8 months have been the most enjoyable hobby time I have spent doing anything. If I was getting angry I'd just hang it up and move onto another sport.
