Even if you don't know how to "cook", bake, saute, grill, boil, etc., it's a great thing to do because it makes you feel something. Hopefully you aren't just frustrated when you're finished! Start simply- don't try anything super complicated- and work up from there. Ask someone that can explain it to you. Clean up after yourself as you go along. When you're finished, hopefully, you have a sense of fufillment!
Just part of living, sure, but isn't it worth a little effort to make the eating part of life wonderful?
