I offer this suggestion to the world at large as someone who suffers from often having too much to say. If it doesn’t work for you, ignore it, but I can attest to how much it has helped me in the last few months.
If you’re like me, most of the people that you contact are stressed for time and manage their lives via their Inbox. Keep messages short. Say what needs to be said, and get out. Lose adverbs. Ignore explanation unless it’s critical. If someone has a question or needs clarification, allow them to be responsible for getting that information. Break multiple messages or issues into separate short e-mails.
It’s made my own correspondence much more efficient and given me more to talk about and more time to interact with the people I’m e-mailing when I do get to see them.
