I totally agree. If you want to learn how to cook, well, cook!
If you never cooked before, don't be afraid, the kitchen won't bite

Start with something simple, like take a frying pan, put some oil in it, heat it up, put a nice piece of meat in it, cook it until golden brown then season it with whatever you like. You can't go wrong with plain fried meat. If you a vegetarian, take a few potatoes, peel them, cut them up, put them in a pot full of water and boil until soft (poke them with a fork every now and then to test). Pour the water off, and season with whatever. There you go, your first self-cooked meal.
If you feel like leveling up, just stand in the kitchen, shout "DING!", turn the lights on and off a few times, and then try
adding to the recipe. For the fried meat, try coating it with beaten eggs, flour and sesame seeds (in that order) before frying. For the potato, after pouring the water off, (while the potatoes are still hot) warm a glass of milk in the microwave (not too hot), drop a stick of butter into the pot, pour the warm milk and then mash the whole stuff with a potato masher. There you have it, some nice fried meat with mashed potatoes.
Some tips from a gamer cook:
Don't worry about measurements and precise seasoning, forget the cookbook until you feel comfortable in the kitchen. Just grab some piece of meat or veggie and try to make the best of it! It
doesn't matter if you put in one and a half tablespoon instead of one, or cook for twelve minutes instead of ten. Cookbooks contain recipes for
someone else's taste anyway. Be adventurous, experiment with different spices, cooking times and ingredients, make it taste good to
you! You can even try extreme combinations, like adding a little soy sauce or tabasco to your chocolate pudding, it might actually taste good! If you are not sure, use
less salt and spices, remember, it's always much easier to put in some more afterwards than to take it back out
I hope I helped a little...
