"The main idea here is that your life is the sum of your experiences. This just means that everything you do in life—all the daily, weekly, monthly, annual, and once-in-a-lifetime experiences you have—adds up to who you are. When you look back on your life, the richness of those experiences will determine your judgment of how full a life you’ve led. So it stands to reason that you should put some serious thought and effort into planning the kinds of experiences that you want for yourself."
