Cooking is an inexact science to a degree. It's usually (not always) is passed to one person from another. Find a friend/family member who cooks and ask for their help. Take it as a given that you are going to screw up from time to time, but sometimes screw-ups spawn new dishes. Experiment, you will find your own style.

Baking, on the other hand is a science. Follow those recipes until you get really good or it wont turn out the way you want it to.

Good luck
