Your parent is not your enemy. Your teacher is not your enemy. Your boss is not your enemy. The other team at work is not your enemy. The corporation is not your enemy. The other political party is not your enemy. Or, more accurately, YOU are not THEIR enemy. At best, you're an NPC in their game. Many of them probably even want to help you, because you are another person in the world, and that feels good.
I take back what I said about this being basic. The first steps (learning your parent, teacher, boss are on your side) is pretty basic. But applying this concept to more complex systems, like corporations and communities, can be pretty advanced. But at the end of the day, what it means is that, most of the time there isn't a conspiracy against you, there are simply incentives that you don't understand.
