In order to populate your foxhole with the right people, you must first know who you are as an individual. That means shaking off old belief systems—creaky concepts of the world and your place in it—that no longer serve you and the habits and lifestyle that you’ve outgrown. Any ideas or interests that were impressed upon you by others, whether they be your family, peers, or culture, must be examined consciously so you can see through all of them and discover your own unique individuality.
