Do you know the inspirational story of Chris Gardner? His life story is the subject of a film starring Will Smith and his son Jaden – The Pursuit of Happyness (and that is the correct spelling).
Essentially, in San Francisco in 1981, Gardner loses his home, his marriage fails and he ends up homeless with his 5 year old son and only $22 in his pocket. The circumstances are immaterial, but suffice to say he embarks on a one-year internship with the aim of becoming a broker at a large brokerage house. Despite having very little money and having to sleep rough (often in homeless hostels) he manages to care for his son and secure a post. He eventually went on to found his own brokerage and secure his own personal fortune.
