Navigating life is about getting through each day without having any regrets about how you spent it. Make sure you enjoy your days and find them as fulfilling as possible. Beyond that, to give your life meaning you need to find out what it is that makes you happy. That is different for each person, although work and love of family are two key concerns for most people. Ideally, in an altruistic world, the things people find to make them happy will also make other people happy, and improve their lives in some ways. I think that is something that is becoming more important � people increasingly see their happiness, and the meaning in their lives, as bound up with the happiness of others.
