Since you are just getting started at the whole cooking thing. My very first suggestion is getting your hardware all setup. You are going to be less successful in the kitchen if you don't have the proper equipment to cook to begin with! like anything else in life, it's the right tool for the right job. here is my list of kitchen items you simply cannot be without.
Chef's Knife
don't make a mistake and go out and buy a fancy set with all the steak knives and stuff in a wooden block. spend $100 and get a single middle of the road quality real chef's knife and steel (sharpener). this is arguably the most important tool in the kitchen, so do it right.

now that you have a solid knife, you need something to cut on. stay away from glass or plastic -- just go with good old fashioned wood. the bigger, the better. i personally use a 16" bamboo block with grooves.

get yourself a 8-10" coated non-stick pan. you want this pan to make stuff like eggs or bacon in. buy a nice one and NEVER EVER use anything on it but plastic utensils. i have had the same non-stick pan for 3 years and it doesn't have a single scratch on it. learn to take care of your equipment and it will last you a lifetime.
Saute Pan
some things (actually most things) you need a good ole stainless pan. when you wanna brown steak in oil and butter - stainless is the way to go. a stainless pan works differently since it retains more heat than a non-stick, and can transfer the heat better to your food. it goes without saying here, you get what you pay for -- try for a copper-bottom to retain and disperse heat better.

slotted spoon, regular spoon, and 2 sets of tongs -- all high quality stainless. 2 spatulas - plastic or silicon.
With those items at your disposal, plus maybe a boiling pot and a colander, and you should be able to tackle anything. Having the right equipment will give you a sense of confidence and rules to work within. if you have pride in the toolset, you will be harder pressed to not cook.
as far as the cooking goes, many people's first advice is the right one -- just keep trying. you will fail and you will succeed, but most importantly you will learn. dont give up! the second most important advice i can give you is this:
use more heat. i would say almost everyone i know who cooks does not use enough heat. of all the foods most people eat, most of them require the highest setting possible on the stove. when you cook meat, you want to cook the exterior as fast as possible with the highest heat possible (called searing) as it locks in the flavor. using medium heat will only server to dry out your meat so it tastes like sand. same goes for vegetables -- use high intense heat. the only time you need any other setting other than "high" is if you need to simmer rice or a reduce a sauce or something. but if you are gonna cook something -- cook it.
all that said, i would like to introduce you to an excellent online resource for simple cooking and preparations. the thing i love about this guy is that he tries to use ingredients you can actually find, and puts them together in a simple way. most of the stuff on here isn't exactly the kinda stuff you should be eating for strength training, but it will help to give you a feel for how things go together, and what flavors they make. enjoy!
