Understand that all emotions serve you. Those you once thought of as negative emotions are merely calls to action. For example, if you feel frustrated it means that you believe things could be better, and they're not. This is a call to action telling you there's something you must do to make this better now. This "negative" emotion is actually a gift if you use it effectively.
