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.
Tony RobbinsThe ultimate success formula: I) Decide what you want (Be precise! Clarity is power) II) Take action (because desire is not enough) III) Notice what's working or not (You don't want to continue to expend energy on an approach that's worthless IV) Change your approach until you achieve what you want (Flexibility gives you the power to create a new approach and a new result.)
