Becoming a successful manager is a difficult enough thing to accomplish.  

So why would we want to jeopardize it once we achieve it? But research  says we unwittingly do just that when we withhold or try to bury one  thing about ourselves in particular – our failures. Yes, you heard me correctly – we’re supposed to tell people about the things that we’ve done wrong and the mistakes that we’ve made. 

This is not an easy thing for any of us to do, but it turns out that in order to be a good manager it is something that we do need to do.
