An important tip for communicating better in business is to avoid giving too much information.
This is hard for many small business people and tech workers, because they are experts in their fields, and enjoy sharing their knowledge. However, many of the people they need to talk to don't have the same level of knowledge, and are focused on solving a specific issue.
It is better to communicate only the information that the recipient needs.
