"It was nothing new" seems to be one of the common comments made about every "new" marketing or self help book, thread or statement made. While true (there is nothing new under the sun), it's a bit misleading because everybody needs reminding or enlightening about most topics.
I read that and thought about how I interact with my customers. Most of my time is spent teaching them about the differences between me and the other cleaners and what I do to set myself apart. After reading the article, I think I could accomplish the same thing if I spent more time asking them what their concerns were and what they were expecting from me. I would still have met my needs, but left them feeling that they have found a cleaner that is focused on their needs.
Nothing new, but very important.
