Be Brief to Clear Up Troubles.
Be brief in conversation. Keep your stories short; don’t drag them out. Skip a lot of the details you might want to include. Make each a short short story. It is the timing—coming to the punch, or the end, quickly and almost unexpectedly—that keeps people interested.
If you cannot interest others in what you say, you may be fairly certain that you are taking too long to say it. Make it brisk, not long-winded. Most of us are more long-winded than we realize. I had to learn this the hard way. Now I don’t bore audiences because I have notes for many more things than I can possibly say in the time allotted. So I have to breeze through the meat of the talk and have no time to pick daisies or cut paper dolls by the wayside.
Being brief keeps conversation interesting. If you want the minute details, read a book.
