crazy?

Is it normal to do things you're not good at? I don't mean things like cooking when one's skills limit them to mac and cheese and hamburgers. And I don't mean the essential things in life either, like a part of your job you struggle with.

Rugby has always been such an uphill battle for me. I wasn't an athletic kid. Hell, I was the "easy out" kid. The one that was continually picked last in grade school gym class; the one noone wanted on their team because she was slow AND couldn't catch (or see for that matter, since glasses weren't allowed in gym without goggles, and THAT wasn't going to happen). I picked it up in college for a variety of reasons, the most obvious being that rugby accepts everyone, which is important if you're looking to play a sport and have literally zero athletic experience. Hell, compared to the fall of 2000, I'm an Olympian these days.

But lets be honest...not so much. I have a good grasp of the rules, the strategy, the game in general. I'm not THAT out of shape. I'm reasonably strong for my size (though admittedly weaker and slower than when I graduated college, though I plan on finishing fixing that this winter). I'm dedicated, passionate, and a pussy. I've been giving this a lot of thought lately, as it's occurred to me its been about 6 years....and I'm wondering if I'm doing the right thing by still playing. Is it time to move onto somewhere where I have a real shot of improving, like running (not that I'll ever qualify for Boston, but I'm pretty confident that I could make some improvement on my current times, and I do want to do a marathon), or triathlons (though I'd need to improve my swimming...and buy a bike)? Or do I keep sticking it out, and find some way over this big huge mental block that keeps me from running and hitting with the vigor that I know my body could handle, the vigor that happens on the (rare) occasion I stop thinking and just go. How do I capture that vigor, make my body just go instead of holding back and letting people push me around (and I mean that in the physical manner)?

And back to my original statement, is this normal in general? Do other people put themselves in these situations, make themselves look like jackasses on a regular basis, work hard for minor victories that are a huge deal to them and inconsequential to anyone else in their immediate vicinity (ie. when I somehow tackled the wing (right off a breakdown) on Sunday, even if it was a smidge high)? Am I crazy for not pursuing a hobby I'm better at, like scrapbooking or crocheting or baking?
