In a way they are mutants, they are different from others. And they follow their own drummer. We know what that means. And are we all like that? We are not like that. If you are, then it would be well to recognize that there were others before you. And, people like that are not very happy or content, until they are allowed to express, or they can express what's in them to express.

That's how we continue on, and will improve our lot in life, solve the problems that arise. Partly out of necessity, partly out of this drive to improve.
