That the open minded person is a person who put things in the right places, when I say positive person I refer to the person who introduce ideas that flourish his/her community like fighting prostitution, drugs, bribery, cheating,...etc.
A negative person to me is a person who says that is normal to have prostitution, drugs, bribery, cheating, ...etc.
Of course there are ways to define a positive and a negative person.
A very important point is that the positive person provide solutions for a problem and take precautions to eliminate this problem in Future.
