How to answer this kind of questions:
Why am I so stupid?
It is not a valid question. It is not the case that there is a pre-existing “I”, to which we can assign some qualities such as stupidity. Instead, I am the sum of all my qualities, including the quality of being stupid.
This kind of questions are like
“Why does a triangle have three angles?”
To be not stupid, the correct approach should be,
“I am stupid. So I have to change my ‘I’ in order to be not stupid.”
Although you cannot change the number of angles of a triangle,
you can change the figure itself, replacing it with a rectangle.
