What does it mean to dwell on trifles in Duke Zhou?

Dreaming of trivial things, although it is not the fault of bad luck in love, but I can't move freely because of trivial things. These two days can't leave each other alone, at least moderate comfort is necessary. In addition, in the past two days, I have been overly sensitive to other people's unintentional words, and even have a tendency to lose self-control. Don't pay too much attention to what others say, or others will think you are making a mountain out of a molehill.
