Pam, I know exactly what you mean, sometimes it does not matter the size of the project to illicit that feeling of accomplishment. I too have been a DIY'er around the home. Previously my ex husband and I had a history of knocking down homes and building new ones in their place and I picked up all kinds of skills and did projects that I could never have imagined that I would.

I've done demo work with a jack hammer on concrete, built decks, installed fixtures and done finish carpentry work. And here a little thing like a tire makes me feel on top of the world. It's not the size of the task it's the self sufficiency that comes from the task that is it's own reward.
