Interesting article, thanks for sharing it. I'd have to say that I own agility, not the other way around.
While there are certain trials I plan into my life (the ones hosted by my club and a small handful of AKC trials) if I didn't get to them, like the local Sheltie club's AKC trial, I wasn't distraught over it. The friend's wedding I went to instead was MUCH more important.
A good example of this is when I went to CPE Nationals this year it wasn't because I expected to win any High in Trial awards but because I wanted to experience a large national tournament with Edan. We only Q'd 5 out of the 9 runs and, honestly, the only reason I cared about the NQ's was because the faults occurring were atypical of Edan's performance and I was concerned
about him and why it was happening rather than a 'poor showing' on course.
Even with only 5 Q's I had a blast because I got to spend quality time with Edan and hang out with some of my agility friends from the local trials. (I was even made an honorary member of "Team Ohio"!

My friend Brenda said if she'd have thought of it she'd have gotten me a team shirt.)
Too much of anything isn't good. When obsession starts to take over it's really time to step back and take a good hard look in the mirror.
