I thought this was an interesting and very thought-provoking article. It includes sound advice for aspiring executives everywhere. 

Most self-improvement articles focus on what things you should be doing, and characteristics you need to develop, in order to bring greater levels of success. How about things you really should stop doing? 

I spend an enormous amount of time interviewing executives, and its amazing how many display some of these negative characteristics. Getting rid of some/all of these bad habits is likely to be a great deal more productive in the pursuit of one's career goals than constantly striving to develop new skills and attributes.
