If you say something to a
whole group of people, you can't be sure everyone is
listening. It is preferable to personalize and
individualize your messages by saying things as a volume and
distance that can be comfortably heard by one or two people
and then repeating where it is necessary. People will
take you more seriously if they feel that they are being given
individual attention.
Personal notes are more
effective than impersonal memos. Your own handwriting
personalizes more than a typewritten or dot-matrix memo.
In situations where many
people occupy a single room, such as in seminars, board
meetings, and classes, it is even more important to privatize
communication.
