When to leave the table

I think I am gradually following this rule: no matter what happens in my life, no complaints,no explains.
Suck everything up and keep moving forward.

My favorite writer Yishu always says, it doesn't matter much when you enter the game, and it doesn't matter whether you get good cards or not either; the most important thing is, you need to know when and how to leave the table, with the best gesture and the best style, and do not expect to get any paybacks and do not take anything with you when you choose to leave.

Yes.It is bloody true. And I am trying my best to be a mentally noble person.
