One must make "timely stop loss" a life creed for everyone.

Cut off the wrong direction orders,
Resign from an unsuitable job,
Leave the out-of-place circle,
Say goodbye to unsuitable relationships and leave unsuitable people.
In this way, do not overly reminisce about sunk costs.
It's not scary to take the wrong bus,
You can't just get on board because you've already invested in the coin.
I just can't bear to let it go.
In life,
Learn not to engage in meaningless internal friction in everything.
is a great wisdom.
The longer you stay in the swamp, the deeper you get stuck.
The more you get entangled in some small matters, the more you lose.
