Never get too sold on your own theories. After all, theories are just theories, not realities.
Everyone who knows me well knows that I'm full of theories. People who think manufacture theories. At least that's my theory.
The problem with theories is that they are inevitably proven to be false - or at least to have exceptions.
What do we do with our theories when they do not prove to be fact? Some of us stick with them. We preach them, propagate them, and push them on other people even though in our heart of hearts we know our theory doesn’t work. It is a form of intellectual myopia.
And why do we engage in this mental dishonesty? Because we are afraid of developing new ways of thinking.
