What's the meaning of jumping into the river with wood?

The moral of jumping into the river with wood is to leave yourself a way out no matter what you do.

I hope to think carefully before doing something, and there are ways to deal with it regardless of success or failure. Worrying before winning is a very important attitude towards life.

Will not be overwhelmed by sudden failure. You can face it calmly. Face all kinds of difficulties in life, solve them and grow.
