I've gotten to the stage in my life where as much as I HATE to get my hands greasy, I've come to the conclusion that I need to learn how to do basic maintenance myself rather than waiting on my hubby. But, I'm not sure what all that actually is. I know I need to learn how to change my own oil. And, I should probably learn how to change tires on my own-especially since I need a new back tire at least once a year. But, what else should I know how to do, and how's the best way to go about learning how to do it?
