Getting out of a fixed mindset can be difficult. What happens over time is that people learn certain habits or patterns of beliefs that are tied into specific experiences that are often painful. These experiences compound until the person becomes convinced that life is just the way it is and you have to make the most of it.
In fact, you will find that many people have little personal mantras or ways of looking at the world. They might say that “life is a battleground” or “work hard play hard”. These idioms have little to do with the way that the world is and everything to do with the unique mindset of the individual. Either way, the person needs to adopt strategies that will help him or her out of a very fixed way of looking at the world.
