1. Having unrealistic expectations or goals. Both our ancestors and us sometimes struggle with deciding what we want to do in life. Sometimes the expectations and goals we set for ourselves are just out of our reach. For example losing over 30 pounds in a month, or making 1 million dollars a year with an average job and hours. Humans want a lot of things that they might not be able to achieve, which makes us stress over it. We want to look a certain way or live a certain way that we thing would bring us happiness, without it, we believe that we are not worthy, so we stress about achieving it.
