Many of us are familiar with the timeline feature in Facebook. I suggest that you develop your own timeline – not to share with others, but for your own benefit. Simply list the major, important areas of your life and then what were you doing at different points of your life in regards to that particular area. Those are also the areas of improvement where you can save time and get better organized or spend your money better.
List timeline categories: house, car, school, relationships, sports, trips/entertainment, big family events (births, deaths, marriages), work, financial situation, family and friends, pets, health, etc.
