Why will some people succeed while others fail? If you have ever participated in a team sport as a youngster you might recall that some players always got to play more than others. These players where often those with the best skills and therefore the coaches preferred them over other less skilled players. As a result, these players would become better and the others had to work harder and often failed to improve in order to catch a spot on the team. This effect could be caused by something called the self-fulfilling prophecy.
How do you explain someone actions and how do you explain your own actions? If you give it some thought you might acknowledge that how you explain them are very different. For example, someone is late to work because they are lazy or because something happened on the way to work? How you understand your and others actions will alter how people are perceived.
