Well as a professional...you don't have a choice. Like it or not, this is what you chose to do every day so, you have to put on your happy face and slip on your apron and get to it. There's no room for feeling like you don't want to cook when you have a lot of folks counting on you for a meal. You're being paid to perform a duty. You have to do what's expected whether you feel like it or not. It's not the same as cooking at home.
