Information overload refers to people receiving more information than they can effectively process.

As a sender, make sure every message you intend to send is meaningful and important to your receivers. As a recipient, take steps to control the number and types of messages you receive. Don’t activate visual alerts for incoming messages unless you absolutely need to know the instant a message arrives; each alert breaks your concentration and requires time for you to refocus. Many systems have powerful filtering and tagging capabilities that can automatically sort incoming messages based on criteria you set. Use this feature to isolate high-priority messages that deserve your attention. Also, be wary of subscribing to too many blog feeds, Twitter follows, and other sources of recurring messages. Take care when expanding your social networks online so that you don’t get buried with inessential posts and updates. Identify the information you really need and focus on those sources.
