What do you mean by internal friction between men and women?

Internal friction means internal friction. Self-internal friction is mostly due to people's non-acceptance, entanglement and criticism of themselves, which leads to mental and physical consumption for self-reasons, which is a kind of harm to individuals.

Many times, we will worry too much about the future and guess what others think. Although we think about it repeatedly, we can't change the status quo in the end. In fact, this situation is meaningless. It belongs to a kind of self-friction, which will cause us to have a lot of negative emotions and feel worse about ourselves, but we are deeply involved in it without knowing it.
