The way of fools seems right to them, but the wise listen to advice

Proverbs 12:11-28
From the fruit of their lips people are filled with good things, and the work of their hands brings them reward.
The way of fools seems right to them, but the wise listen to advice.
The words of the reckless(魯莽) pierce like swords, but the tongue of the wise brings healing.
Anxiety weighs down the heart, but a kind word cheers it up.
In the way of righteousness there is life; along that path is immortality(不朽).
Wisdom and folly - the wise man and the fool.
Thus us the main strand of whole book, the subject of the first nine chapters. The sayings point the contrast between wisdom - living by God's standards, keeping to what is right, and folly - people willfully going their own way.
Wisdom leads to life and all that is good - folly is a mere half-life that ends in death. The verses  detail the wise course of action in many different circumstances. They outline the character of ' the wise' , in contrast to the life and character of the 'fool' who shut his mind to God and reason.
Why?
The way of fools seems right to them, for they did on their own mind and own knowledge. But wise man listen to advice, listen to other perspective minds.
Before saying anything be aware of what is the consequence will be. Talk it with love and careful mind.
How?
Be a wise man and listen to advice.
