When you say less, you emphasize more.
You may not be able to say more, but what you do say will be heard.
Half attention becomes full attention.
Scanned writing becomes writing that is read.
Discarded opinions become opinions that are taken into consideration.
Saying less increases the emphasis on what is said. Saying more increases the time, effort, and expense required to listen.
Loud communication is repulsive. Succinct communication is inviting.
You are statistically guaranteed to reach more ears by talking more; it's easy to get attention by publishing every day. But talking and publishing every day are not the only ways to practice and improve communication.
You can write and ruminate every day without talking and publishing every day. What you do makes up the difference between receiving attention and holding attention.
Would you rather have people hearing you or listening to you?
