In a non-stick skillet, melt the butter. Once melted, add the egg mixture. Leave for 10 seconds. Using a rubber spatula, go around the edges, make sheets through the middle and constantly stir together. Cook until it almost looks good for you. Maybe, around 5 minutes. Next, around 2/3 of the way through cooking, throw your cheese in and mix, the cheese should melt into it quickly. Then, when very nearly done (like 15 seconds before) for you, take the pan off the heat because the pan is hot so it will continue to cook the eggs. They should be fluffy and creamy once completed cooking.
