The greatest value of solitude is not silence, but giving a person's thoughts the opportunity to complete a closed loop.

Most people's ideas are just beginning to sprout when they are interrupted by social interactions, public opinion, and information flow.
Only those who can be alone for a long time have the chance to refine a vague thought into a unique understanding, then turn that understanding into action, and finally into results seen by others.
The so-called uniqueness is often not generated among the crowd, but grows out of solitude.
