Identity is a word society uses to refer to who they are as an individual.
The overriding feeling associated with a lack of identity is usually being unsure of oneself. An aspect of this is being unable to make up your mind. What you do and don’t like? These are feelings that can create a large amount of anxiety because there is a feeling of being ungrounded.
Identity helps to ground an individual, no matter what the situation, if a person feels they know themselves they are likely to get more out of that situation. Essentially having an identity is about how well you know yourself which then leads to a knowledge of what you want out of something as opposed to not knowing. Which can result in opportunities passing you by.
