When you are young, you should talk less, learn more and do more. Because young and frivolous people are easily frustrated.

The reason why people are always arrogant is because the elderly are stable and need to drive others to do it together. This is like holding an activity. Young people have no experience and can't make plans, but old people don't make plans. Can this activity be successful?

Arrogance here is not arrogance, but the meaning of presiding over the overall situation.
