This shows a baby being born to the ideal American family. His parents achieved the American Dream and expect the same of him, even though he may not want to follow in their footsteps.
As a kid he can do anything he wants and is encouraged to follow his dreams. He is happy and is encouraged to do whatever makes him happy and that is his main priority, the harsh reality of life has not hit yet.
The harsh reality of life has hit, when you get your college degree. A lot of people end up settling when choosing to do their college degree major. Rather than choosing to do what makes them happy, they do what makes them the most money.
The man achieves the American Dream but it is not what he wants in life, and he feels unfulfilled.
The man lives his entire life unhappy and slowly slips into depression and unhappiness.
The man has died and looks back at his life and wonders what could of been.
