You are the most important person

Everyone has needs, and the only person who knows exactly what you need at any moment is yourself - no one else.

This means that we can't know what others need every moment either.

So we need to encourage others to behave in accordance with the fact that they are the most important person in their life.

If we each did this, we would be far more effective in all aspects of our lives as partners, friends, parents etc.
