They learn to conceal their insecurities and envy. If we take this appearance for reality, we never really know their true feelings, and on occasion we are blindsided by their sudden resistance, hostility, and manipulative actions.

On the other hand, since appearances are what people judge you by, you must learn how to present the best front and play your role to maximum effect.

Sometimes the changes that are generated in a revolutionary period are rather trivial and do not last past the cycle. But sometimes, from a strong crisis, a revolution forges something new that lasts for centuries and represents progress toward values that are more rational and empathetic.

If for any reason the cycle stopped, we would be doomed.
