There are several reasons why people post selfies on social media. One possible reason is that selfies can become addictive, especially if people believe that the number of likes they receive is a measure of their self-worth. Each time a new like is posted, it can trigger a positive feeling in the individual, leading them to post more selfies in order to continue receiving this feedback.
Another reason why people post selfies is to boost their self-esteem. People with low self-esteem may believe that taking and posting selfies will help them feel better about themselves in the long run. In some cases, people may also post selfies as a way to connect with others or to share their experiences with their social network. However, different people may have different motivations for posting selfies, and some motivations may be healthier than others. For example, investing heavily in editing selfies or becoming obsessed with taking and posting them may be problematic for some individuals.
