We are born helpless. We can't walk, can't talk, can't feed ourselves, can't even do our own damn taxes.
As children, the way we're wired to learn is by watching and mimicking others. First we learn to do physical skills like walk and talk. Then we develop social skills by watching and mimicking our peers around us. Then, finally, in late childhood, we learn to adapt to our culture by observing the rules and norms around us and trying to behave in such a way that is generally considered acceptable by society.
The goal of Stage One is to teach us how to function within society so that we can be autonomous, self-sufficient adults. The idea is that the adults in the community around us help us to reach this point through supporting our ability to make decisions and take action ourselves.
But some adults and community members around us suck. They punish us for our independence. They don't support our decisions. And therefore we don't develop autonomy. We get stuck in Stage One, endlessly mimicking those around us, endlessly attempting to please all so that we might not be judged.
In a "normal" healthy individual, Stage One will last until late adolescence and early adulthood. For some people, it may last further into adulthood. A select few wake up one day at age 45 realizing they've never actually lived for themselves and wonder where the hell the years went.
This is Stage One. The mimicry. The constant search for approval and validation. The absence of independent thought and personal values.
We must be aware of the standards and expectations of those around us. But we must also become strong enough to act in spite of those standards and expectations when we feel it is necessary. We must develop the ability to act by ourselves and for ourselves.
