Prospect for the best information sources. Though there are notable exceptions, often the more costly an information source, the more time-efficient. Watching television news might be free, but we all know how easily TV can turn into a mindless time sink. Don't feel compelled to read everything that crosses your desktop. Filter out the junk.
Computers can be a help or a hindrance.
By connecting to the Internet, you can quickly tap into a gold mine of authoritative information relevant to your needs. Or you can waste hours scanning the web sites of hucksters and hobbyists, reading e-mail and Usenet messages written by rumormongers and idle babblers. If you're visiting a new web site, look at it the same way you'd scan a book before reading it. Before diving in, check the table of contents and author's biography. But make sure you read the site's search procedures first, or you might have to wade through scores of irrelevant hits.
