What do you see around you?
You will see the good, the bad, the different and the indifferent.
When you read or hear the news, you will notice more bad news reported than good news.
Around your family, friends and work stakeholders you will see a variety of personalities that will colour your judgement of the world.
Despite all of the above, your ultimate view of the world will be determined not by how the world is, but how you are! This is because the processing of the world view is in your domain and usually you see around you the way you are as a person.
If you are a good person you will see more of the good in others. If you are a bad person, you will see more of the bad in others.
