Hobbies and self-sufficiency

In order to get away from the computer for awhile, I spent the morning putting my EarthBox Garden Kit together to grow tomatoes. It grows great-tasting tomatoes that I use for snacks and sandwiches and I have to say that in addition to being healthy, I kind of feel more self-sufficient which is a plus these days.

Do you have a hobby that gives you a sense of self-sufficiency?
