I've often been called a pessimist and a very negative person. I have to disagree. I have such high hopes of humanity that I'm continually disappointed, hence coming across as a negative person.
I do believe we live in a world of people who are manic optimists. They take a futile "fake it 'till you make it" attitude to happiness. That approach might work when you've got a case of the Mondays, but it doesn't do anything if there are fundamental parts of your life you are unhappy with. And rather than tackle or approach those, the manic optimists stay on the surface, obsessively convincing themselves they are not as miserable as they are feeling.
That is where the clash with people like me come, when they suggest that things could be better, the manic optimists are confronted with the fact that the status quo is not as satisfying as they try to believe it is. So, to maintain their own delusions we are branded as pessimists and troublemakers.
And I think this conflict is the very reason there is so little change and improvement happening in the world. The manic optimists are clinging to the present state of affairs, preventing the "troublemakers" from doing their thing.
