You must remember,

People have nine things they do not compete for:
Do not argue with parents over words,
Do not compete for face with friends,
Do not争高低 with leaders,
Do not争道理 with villains,
Do not争对错 with partners,
Do not争穷富 with relatives,
Do not争名望 with noble people,
Do not争脾气 with children,
Do not争得失 with yourself.
Remember,
Behind money is matter,
When you do things to the extreme, money will come.
Behind matter are people,
When you treat people well, the matter naturally gets done.
The first lesson in life: Accept that your parents do not love you,
The second lesson in life: Accept that your partner does not love you,
The third lesson in life: Accept that your children do not love you,
The fourth lesson in life: Learn to love yourself.
