Your mission statement is a blueprint of your vision for your life. When thinking about writing a mission statement, be specific. If you want to have a happy, meaningful life, ask yourself what actions you will need to take and what values and purposes you must have to drive those actions. What is your raison d’être? What is the focus of your life’s work? How do the things you do and the way you treat your family and other people reflect your core values? Maybe you prefer to react as life comes at you. But if not, clarify what you want to do with your life. What will give you lasting peace and happiness, when, at the end of your life, you look back at how you lived?
