Good cooking almost entirely depends on technique, Tapslog. In fact, for my cooking classes I define cooking as using good techniques to manipulate good products towards a desired end.
Recipes, per se, are actually of little importance once you share that view. They are guidelines, not instructions.
With that in mind, first and foremost in importance is knife skills. Learn how to sharpen, maintain, and use your knives, practicing as much as possible (potatoes and onions are great for this) to achieve a level of proficiency.
I believe knowing how to break down proteins is very important. You're already on your way in those terms with fish. Now learn how to do it with a chicken, and with primal cuts of beef, etc. Butchering, btw, is a whole different set of knife skills from prep work, so you'll be developing in two directions.
To me, there is no way of prioritizing which techniques to learn, as it depends so much on what you intend cooking. If forced to make such a choice, I think I'd put frying techniques at the top (i.e., searing, sauteing, pan frying, deep frying) because so many dishes depend on them. I'd follow them by learning moist heat techniques (i.e., steaming, poaching, braising, boiling).
Why the emphasis on technique? Because if I teach you a recipe for, say, pan-fried chicken you'll be able to make one dish. If I teach you how to pan-fry, however, you'll be able to make hundreds of dishes.
Along with techniques I'd want to learn the effects changes have on a dish. For instance, to pan-fry chicken breasts, pound them slightly so they are evenly thick. Then set up a three-bowl breading station. Flour goes in one bowl; beaten egg in the second, breadcrumbs in the third.
Bread a chicken breast and pan fry it. Then start running changes. What happens if you season the flour instead of or in addition to the breadcrumbs? Does anything happen if you mix cornstarch with the flour? What if you add hot sauce to the eggs? What if, instead of breadcrumbs you use ground nuts? Or crushed cereal? Or Parmesan cheese? Or potato flakes? Or....well, you get the idea.
What if you cut a pocket in the breast and stuffed it, then pan fried it? Now you can run through the breading changes and have an addition option of what to use as a stuffing.
Lookee here. We've just made 15-20 different dishes, none of which used a recipe, but all of which resulted from the technique called pan frying.
The only other advice I can offer is: don't be in a rush. You can't start learning today and have 20 years experience by tomorow.
