Commerce creates optimists

Have you noticed that most self-employed people and people who have created their own businesses are positive?

Commerce requires a self-honest evaluation of the world.  A good business person must notice trends in order to make good investments and satisfy customers.  That requires optimism. 

Being self-honest about trends and patterns in the society around us means seeing reality, seeing opportunity, seeing positive directions and having enough confidence in one's own views to take action.  Business people also see negative trends. But the key element in their perspective is to see both negative and positive trends over time.
