Morality and politeness are a source of strength. Take care of them. After all, if you lose your power, it will cause fear. Fear will sublimate into procrastination and laziness, robbing you of the power to move. The power of movement is Faith and the source of experience. What will you have left? Fear, laziness, anger, despondency, impotence.
Politeness is when you trust people. Faith is love. Love people politely. Not to love people, not to believe them, is to feel fear. Fear is sublimated into anger, doubt, and aggression. This is all very impolite.
To keep your schedule, you should love what you do. The fact is that love is respect for other people's borders. The boundaries of entities are defined by time. It is impolite when one entity violates the boundaries of another.
When you try to bark at other people, other people bark in reply. It's all simple. Polite and well-mannered people (from the best of motives) try to speak to you using your native language and words that are easy for you to understand.
