Self-development is the only thing that keeps a person from burning out. We all have many needs - the need for certainty, the need for variety, the need for significance, and the need for connection. But, ultimately, we must grow, and we must contribute in a meaningful way in order to feel fulfilled.
Tony RobbinsUnderstand 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.
