One thing I've learned is that it's important to appreciate the lack of bad things. LOL Today I got a blister from the new running shoes I wore to the gym. Yowch. I didn't realize how much I like my feet & how good walking blisterless feels, until I had a blister. Same thing for my headaches, which I get on a regular basis. After a killer headache, the days where there is no pain seem just a little bit sweeter. There does need to be opposition in all things.
