"He  that  walketh  with  the  wise  men:  but  a  companion  of  fools  shall  be destroyed.”

-         Proverbs 13:20

I think that this quote means that, if you surround yourself with good things, you will not be influenced to something wrong. On the other hand of you surround yourself with bad things, you WILL be influenced to do the wrong thing and you will no longer be a CTR person, you will be a CTW person.
