One of the reasons I found it so amusing is that its true: cooking, well baking, is mostly about following directions. Oh sure, you should eventually develop a knowledge of things like heat management, basic needed equipment, knife skills, cooking terms, and some basic skills. You should probably also, especially if baking, know a little about the chemistry of how all those things work. My favorite example of this occurred several Thanksgivings ago, when my husband's family discovered I could make pie. I used a crust recipe known as "never fail" in the family cookbook, and my husband's grandmother spent a lot of her conversation with me over the next day asking me to recite the recipe and nodded along, saying things like, "The vinegar activates the gluten." Of course, I know so little about kitchen chemistry, that I have no idea if that statement makes any sense.
The reason it is mostly okay that I'm not an expert in activating gluten etc... is twofold: most cooks work by trial and error, and most cooking knowledge is handed down. If I don't know something, I rarely go to the internet first; instead, I call my mother, whom I regard as a bastion of culinary knowledge. The other reason is that there are plenty of people out there who know this stuff and make a good living teaching it to others, like this man, pictured below.

Point being that when I started cooking on my own in my teens, I experimented. I did brownies with all kinds of added calories. I did very spicy chicken. I did some pretty damn good baked beans. And if it didn't work out... well, it mostly worked out. There's a learning process with cooking, and a huge part of that process is the ability to admit what you don't know, and to seek that knowledge.
As I moved onward and upward, I started with the basic things: spaghetti, chicken and pasta, hamburgers etc... I can remember being bothered by the fact that there were people who were better at cooking than I. I can't remember when I started to list cooking as a hobby - perhaps when I figured out that I was good at it. I also remember that as I started to want to know more - as I began to admit what I didn't know - I started to love the company of those who knew more about food and cooking than I did. And that openness started to form into richer, more evolved opinions, which evolve into more openness, more desire for knowledge.
In a lot of ways, the cooking I do is both looking forward and back. Forward toward new things I haven't tried. And back toward trying old things in improved ways. Because really, no matter what level of cooking expertise you have, you're going to mess up sometimes. And really, the ability to make good brownies, or good chicken and rice casserole in a pinch more than makes up for the mess ups.
