Creation consists of pairs of opposites or polarities. Call these polarities or pairs two's. These polarities become creative when they interact. For example, how male and female elements interact in order to create more beings. This is how all creativity occurs.
The wise person knows about pairs of opposites and their interactions. Wise persons know how to be creative. In order to lead, the wise person learns how to follow. In order to prosper, the wise person learns to live simply. In both cases, it is the interaction that is creative.
Leading without following is sterile. Trying to become rich by accumulating more and more is a full-time career and not free at all. Being one-sided always produces unexpected and paradoxical results. Being well-defended will not protect you; it will diminish your life and eventually kill you.
Exceptions to these examples of traditional wisdom are very hard to find.
