Most people don't realize it, but happiness exists independent of life’s circumstances. By saying, for example, "My boss depresses me," you become a victim (i.e., you have no choice, your boss depresses you). A Self-Coaching, non-victim response should be, "I'm ALLOWING my boss to depress me."
Bottom line: life circumstances don't bring you to your knees, how you interpret these circumstances does!
Next time you're inclined to feel like life is beating you up, recognize that you have a choice. You can choose to be victimized or you can take charge of what distresses you and be in charge!
