I could do this, but without following a recipe I think it would turn out bland or bad. But you know, that's a temporary problem. I will try this.
Then after you mastered some recipes you;ll have some standby recipes (either written down or in your head) that are yours that you are comfortable with. But you'll probably keep experimenting too.
You will mess up. Probably a lot. You'll make some crappy food once in a while. You'll learn the hard way, but instead of feeling like a failure, look at what you learned from it. Try again.
I also suggest trying some stirfry first. It is extremely simple to stirfry, pretty healthy, and there is a real lot you can do with it - different flavors of sauce, different veggies, meats, etc., and you can buy the veggies frozen so there is very little prep.
I find that a lot of children don't get that kitchen experience while they are young so they grow up clueless in the kitchen about how to even start to prepare meals. I really can't understand this too much. I was in the kitchen since I was old enough to stand upright and hold a spoon helping out, standing on a chair to reach the counter or stove. As a result I'm extremely comfortable in the kitchen. I'm far from a "good cook," I'm average, but having that comfort I think is key.
