Online Cooking Lessons
In the old days, in order to become a good cook for more complicated (and often more delicious) meals, you had to read cookbooks. In most cases, several cookbooks. That was a pretty fun endeavor if you are really interested in cooking, but it was very time consuming and didn't give you many points of view.
Then came Julia Child and we had cooking classes on television. Then more cooking classes on television. And then, omigod, a whole food channel. But you had to watch them, take notes, and then try to fly on your own. Then there was TIVO and other DVR devices, but that was still on television which you may or may not have in your kitchen.
Now we have an online cooking school. Classes can cover all sorts of techniques, recipes, preparations and equipment. You can easily start or stop the class on your laptop--heck you can probably do that with your (greaseless) elbow.
The first important step, in my opinion, is to develop technique. Technique can make the difficult easy. It can make you the master of the leftover. It can let you put together an impromptu meal for the unexpected guest with aplomb and much enjoyment.
For example, because of technique, I can turn a separated Sauce Hollandaise back into a creamy delight. But I learned that 40 years ago and had to read 600 pages to do it. Now it is ever so much easier.
So I recommend looking into online cooking lessons for the most efficient, easiest, private way to become a genius in the kitchen.
