Without your family, without your friends, your connections and your things, what are you? Who are you?
Are we defined by our relationships with others and the roles that we play in society and groups we belong to? Are we who others think we are or who we want them to think we are?
If you are stripped of the people close and acquainted to you, the clothes and gadgets that you own, and the money that you have, would you still be "you"?
If for instance you were thrown into a place where absolutely no one knows you and you have just enough money to live by, how do you think will you adapt? How do you suppose will you be known as once they get to know you?
With relationships and materials taken away, you are left with your true self. And what is left of you as an individual is your personality, attitude, perspective, skills, talents, and education (both formal and informal).
That is your character.
So think about it.
Are you proud of who you are?
