Allow anyone to leave at any time, and also allow things not to go as hoped. Accept the discrepancies between the world and wishes, and calmly admit that you are ultimately just an ordinary person. Be able to take up and let go, the people and events of the past, let them stay in the past, without explanation, without entanglement. Do not try to persuade those whose values differ from yours, respect others, but always remain true to yourself. Have the courage to be disliked, rather than living under the labels of others, it's better to live by your own definition.
