The key thing about cooking is that it isn’t the practice of following directions. In fact, almost all professional recipes suck because they’re geared towards some hypothetical person who’s never tasted anything with more flavor than water. (And I’m not just talking about spicy spices. Garlic and basil are cut down to bland levels.)
Really, all you should take from a recipe are the steps, and just ignore the quantities on the ingredient list. More often than not, you’ll be just as happy to swap out half of what’s on the ingredient list for whatever it is that you actually have in the kitchen.
Cooking is a creative process, and it’s one where achieving the right taste isn’t dependent on measuring stuff accurately (unless you’re baking), but by constantly sampling to see if it matches what you’re looking for. You need to be able to visualize the taste you’re headed towards.
One of the greatest things about cooking, perhaps, is that you get to make all the foods that you can’t find. I used to live in Japan, so a lot of my favorite dishes just don’t exist here. Mexican tortilla soup is a wondrous thing, but there’s no good Mexican restaurants near me. Philly cheesesteak is also a great dish, but again there’s no place nearby. Once you’ve made any of these a couple times, remaking them in a short period of time becomes pretty simple, at least if you follow my advice in the next paragraph.
If you want to cook, especially if you’re only cooking for one, you need to Prep and Freeze. Go to the supermarket and grab all the vegetables that you like/particularly like. Buy a bunch of ziplock freezer bags. Come home and dice all the vegetables into bite sized portions and fill the freezer bags (separating the veggies by type, obviously). Keep these in the freezer. When you have a recipe, just use whatever veggies seem like the ones that would best match the recipe from what you have. When a bag starts to get low, buy more veggies and throw them in.
Keep frozen meats of all types around. You don’t want to keep them in their original packaging, since they’re pushed together and become a single block of stuff when they freeze. Generally you can fit 4-6 meat cuts in a single freezer bag, not touching one another.
If you want to bake your own bread, you can make dough, separate it into small balls and freeze those for later. (I haven’t done this one yet).
If you do all this, you can make full meals very quickly. Dicing stuff and sticking it in the freezer takes practically no time, so there’s not a lot of excuse not to keep it up.
