So, you think you are executive material? Let’s see.
The best CEOs and managers I know never interrupt meetings with phone calls. I know of no good manager who will bring a cell phone into a meeting.
Do you constantly interrupt the person you’re talking with by answering your phone? Bad.
Good CEOs and managers answer email from people they know. People they know. They don’t reply to every piece of spam that drops into their in-box but they do answer people they know. That’s called courtesy.
It only takes a moment to reply to an email. Your reply, even if your answer is ‘no’, might mean a lot more than you realize to the sender.
