I have been thinking about this on and off for a while now and the death of Margaret Thatcher has only reinforced my belief that I don't really have many opinions on anything! 
Just when I think I have an opinion on something, it can be anything; Thatcher, the welfare state, fox hunting, immigration; I will then read another article or speak to someone else with an opposing view and feel like perhaps I was wrong and my viewpoint changes slightly. I often feel like I never know enough about anything to form an opinion. So I read up on things and try and find out more about them, only to find myself less sure of my opinions than I was before!
Does anyone else feel like this? I am sick of sitting on the fence about things, there seem to be so few things that I'm certain of anymore! Am I over thinking things, or just ignorant?
