It is indeed the usual case, but limiting your thinking to the
usual case reduces your opportunity for understanding.
Believing too strongly in the usual case will inhibit your
ability to understand when you begin to explore more
general cases. First you will have to unlearn your beliefs.
If you have repeated them to yourself for too long without
understanding their limitations, you can find it very difficult
to let go of them even when they no longer serve.
It is therefore useful to occasionally remind yourself of
the limitations applicable to your assertions.
