if you're learning how to cook or branching out or feel like you just are not a very good cook or can't cook at all it is so important to know that when experienced cooks say they're measuring with their heart they are lying to you. They are measuring with their intuition, instinct, and experience, all of which are built by following recipes (written or taught by family), experimenting a lot, or some combination of the two: no matter how they learned, they learned it through cooking way more than you have. If you're trying to cook based on instinct or the assumption that you should just be able to figure it out and you don't like how your food comes out or you don't know where to start, find recipes and follow them to the letter. There is nothing wrong with looking up how to scramble eggs or make a stir fry. It will make your cooking better and easier, I promise.
