I guess I'm just quite observant and I pay attention to a lot of things. Human behavior really fascinates me.
That human behavior is more influenced by things outside of us than inside. The 'situation' is the external environment. The inner environment is genes, moral history, religious training.
Human behavior flows from three main sources: desire, emotion, and knowledge.
Situational variables can exert powerful influences over human behavior, more so that we recognize or acknowledge.
One of the key elements of human behavior is, humans have a greater fear of loss than enjoyment of success. All the academic studies will show you that the fear of loss of capital is far greater than the enjoyment of gains.
