Fist of all, I am amazed at how popular my previous post became. There have been over 5000 views of it already. It has never happened to any of my posts before, which tells me that the article really struck the chord with my colleagues. We need to be honest and open about mistakes we make! That's how we can learn from one another! Thanks for all your comments here and in social networks. Your opinion and your experience matter! One of my readers asked to render an account of the ways to remedy those mistakes . I think it's a great idea, and, besides my experience, I am also going to use the experience of my colleagues, shared publicly in their blogs or in comments to the previous post.
