Try it! Re-read any e-mail you’ve recently sent. Then delete the word “I” as many times as you can. The message is still clear. (For example, “Want to confirm our date” rather than “I want to confirm our date.”) The fewer times you use “I” in your messages, the more relevance and punch it has for your reader.
In fact, even in conversation, say the word “I” as seldom as possible. Therapists calculate inmates of mental institutions say “I” and “me” twelve times more often than residents of the outside world. As patients’ conditions improve, the number of times they use the personal pronoun also diminishes. In other words, dropping the word “I” is a pretty smart thing to do!
