You don't need full sets of knives and cookware. A stockpot, a ten-inch skillet, and a two- or three-quart saucepan will cook most of the food you want to eat. Likewise with knives: after a chef's knife or two, a paring knife, and a bread knife, any additional cutlery is just showing off. The trick is to make sure what you do have is of high quality. One really well-made knife is an investment that will last a lifetime, and it'll help you love to cook more than you ever imagined.
