Last week I had to apologize to the people on my list. I had invited them to a teleseminar training that required a password. The first email I sent contained this password; the follow up email did not. I did the same thing on my paid call that week.
One of my students wrote to tell me about this. He wasn’t angry, but he had missed out on two calls that he had scheduled his time to listen to. I apologized to him, and then apologized to my entire list for the confusion this had caused. I knew he wasn’t the only person I had inconvenienced.
Don’t be afraid to make a public apology to the people on your list, if it is warranted. Being big enough to admit when you are wrong goes a long way in today’s world, and especially on the Internet, where people are sometimes skeptical to begin with. This also makes you seem more real to the people on your list.
