Chris Gardner.
During his interview with the stockbrokers, Chris Gardner shows up wearing a dirty shirt instead of a suit! Confidently and without showing weakness, he explains what happened for him to be in that state. His intelligence and enthusiastic conversational skills earn him a spot as a trainee within the company. (inexpressiveness)
Now, the problems of his financial situation are still ever so present. Being a trainee meant that he would have to do work without making any money while competing for the limited space the company held.
He was, for some time, homeless and taking care of his son. They were always on the moveand had no choice but to rely on himself. With this mentality, while working, he does things that saves him time and sets several goals for him to achieve by the end of each workday. (independence)
Always showing up and always find a way around the problem.
Chris Gardner, I believe is a good example of an independent and inexpressive man.
