Negative thoughts can be difficult to get rid of. When a negative thought pops into your head it can cause you to keep replaying that thought over and over again. According to an article from Amanda MacMillan on happify.com, "rehashing negative thoughts over and over in your head, also known as rumination, can be unpleasant and counterproductive—and in some cases, it can even lead to chronic depression." Luckily, Amanda's article discusses ways to help get your mind off of these negative thoughts and focus on things that are more positive.
When a person's mind is full of negativity, they may not see the world accurately. They might have a negative view of themselves, others, and life in general. However, that person comes to recognize that those negative thoughts and beliefs are not true and learns to change them, they can simultaneously learn to change their perspective. Their view of the world might get a little rosier, lighter, and happier.
