Talk less, do more

The longer you work, the more you know how to behave, the lesser you would speak, or, you would refine your words before you talk.

I saw some vivid examples illustrate that sometimes a person speaks something expose his weakness and incapability; or he does something which he thinks it is cute but it is actually irritating from others' eyes.

Of course, it is somehow sophisticated and the should learn from experience. Luckily I improved a lot in this aspect throughout all these years.
