agree jrose, clueless is just about the last word i would use here.

great sentence: "Because the people who are clueless enough to think
they can change the world, might be the ones who do."

not sure what i would change clueless to, but it sure isn't the right word.

Y'all are missing the point. "Heroism" here is ironic. You have to be conscious of danger or insurmountability to be heroic. The clueless stumble upon things in ignorance, sometimes with very positive results.

I grant that cluelessness can have different meaning. A negative example would be the John Lennon variety as expressed in "Imagine"
