I see people every day being driven by money, success, social hierarchy, control, and illusionary importance. It truly is a tale as old as time and we see it as a theme on tv, our daily lives, politics, religions, and so much more. From the small places in life that seem unimportant to the parts that are supposed to have the deepest impacts on our lives. Our purpose is driven by others and not our own free will.
Finding purpose in life is the driving force of most peoples unhappiness. It leaves us depressed when we can't find it, confused when we have lost it, disassociated from our community when the "important" people are disappointed in our paths.
First and foremost, know that your life purpose can change throughout life. You get to choose that purpose. You get to set the parameters to that purpose. You get to embrace whatever purpose you choose to live!
Finding purpose is the next step after finding your authentic self. Its the step that should bring happiness first and foremost. Applying the authentic self to your life, your community, and your career is a key factor in living happily and embracing a purpose for being here.
Know that some years and stages in life we are creating larger purposes and other times the purposes do not seem as important, but they all are. Some years are for quiet contemplation and reset, some years are for pushing ahead and effecting the larger community around us.
