What motivates a person not to act?

So far my thoughts tend to lead me to the conclusion that the main reason most people do not act is fear. Fear of the unknown combined with fear of the known. Most people it seems do not make the choice to change thereby accepting their current situation. This acceptance is not based on liking their life, but rather on the fear of changing to a possible worse life.

Why are people willing to maintain a miserable existense out of fear of change?
