what is there inside a person?

what’s there inside me?

is it tangible? is it understandable? is it logical?

they say, the human mind is at best, incomprehendable. is it really? what gets me is how similar we all are, how you can almost predict to a T what each one of us going to do.. save a few minor details..

is that all there is to it then? minor details? little deviations to a largely established codebase?

then what really lies inside us? the answer eludes me…
