I know that this suggestion is very difficult to implement, but try it:
When thinking of things and analysing them, try not to classify them into categories. Put them on a scale.
For example: Norway is a cold country and Singapore is a warm country.
This classification seems perfectly justified, but it leads to a liking for oversimplification, where we continuously put things and people into categories just for the analytical pleasure of it. Try forming a description of any person you know and you'll get what I mean.
What should be done is to just keep things on a scale and analyse things comparatively.
For Example : Norway is colder than Singapore.
Such a method of analysis keeps the analysis more realistic.
