How does the pursuit of happiness relate to belonging?What themes, ideas and relationships are there that relate to belonging?

One of the critical themes of the film is how individuals perceive those who are on the "outside" of our social order.  Chris Gardner starts out the story belonging to the world of wealth, privilege, and respect.  Through financial challenges, he is relegated to the outside.  His desire to belong to a world of stock brokerage is sustained through his belief in his dreams and the commitment he has to his son.  He is animated by his desire to belong, and his desire to link his dreams to success that comes with belonging.  The film shows that if one seeks to belong to something and this is embedded in their dreams, then it can be accomplished so long as individuals show their commitment and are not afraid to take the opportunities presented.  In this light, dreams and belonging go together quite well.
