Every man his hour.
Humans are interdependent beings. We are dependent on each other for many things in life. We depend on people adhering to traffic rules in order to get from one place to the next. We depend on people to make sure there is food in the store. We depend on people for so many things in life. All you have to do is think through your day and you realize that you need people...hopefully people need you as well.
As we are interdependent, we must get along with people. As the Mishna goes, "אין לך אדם שאין לו שעה". There is no person in the world that doesnt have his hour. Every person has his hour in which he can shine, in which he can give something to someone else.
People with wealth, physical or spiritual wealth, usually are on the giving end. They tend to have connections, resources, and all sorts of other goodies. However, there comes a time where they also fall short, for example when they are in a foreign place. In a foreign city, they dont know anyone nor does anyone know them. At that point maybe even the city pauper could help them out, even if it be for directions. "There is no man that doesnt have his hour!" Remember that, and remember that well.
