Are you experimenting with many dishes at once? Pick one you like, cook it once a week (or whatever your boredom tolerance is), and experiment with that. Try throwing in alternative spices or ingredients, varying salt amounts, cooking times, etc.

IMO, cooking is best learned one or two dishes at a time. After some experience, you'll start to get a broader picture of the art. Think of it like trying to learn "music" from scratch by picking up a different instrument each night - it could work eventually, but you're probably make better progress with a little focus.
