I am an e-mail user. When I first started to use the e-mail system I used to read all my e-mail. I didn’t have much mail. I was very excited about receiving any e-mail. I gave my friends my e-mail address. Soon I had more mail than I wanted. Some of the mail was junk mail. I was worried. I didn’t want my mail to control me.

I’ve tried some methods to help me get control of my mail. First, I check my mail at the same time every day. Also I try to allow myself only 15-20 minutes every day to process my e-mail. This doesn’t always work, but I try. Sometimes I save the messages. Sometimes I just read them, maybe answer a few, and then delete them.

Sometimes I’m not at all interested in a message, so I don’t even open it. I delete it right away. This is very much the way I go through the mail that the postal service delivers to my home.

These methods are very simple. I have some friends who are very clever with computers. From time to time, they teach me new tricks for managing my e-mail. I’ve also learned to transfer some messages to a disk so they don’t fill up my mail files. Then I can read them later and maybe use them in my work. I’m still amazed at what e-mail can do for me! I’m still worried, however, about having too much to read.
