The external forces that gain influence over our identity are the elements of the environment in which we live and the people we live with.
We can arrive at this answer because:
Personal identity is the term referring to the ability of human beings to behave in the same way in any situation.
That identity is something that determines who we are.
Furthermore, identity is formed by the joining of our beliefs and convictions and the influence of external factors.
These external factors are associated with elements that are outside our body, but which have an impact on the construction of our identity.
In this case, the external factors refer to the environment in which we live and the people we live with. The environment can encourage a calm, nervous, quarrelsome, peaceful identity, among others. In addition, people around us can show us new ideas and beliefs that influence the modification of an individual's identity.
