You are perceiving a feeling.
No rational person believes a human can "do anything they want".
I'm certain there are a great many things you would do (that you are not currently doing) if it were truly as easy as snapping your fingers.
Your current slate of "choices" are determined by your history and biology. And your ability to make "good choices" is also determined by your history and biology.
A person born with a low IQ cannot "choose" to have a higher IQ.
