Most of What Passes for Legitimate Entertainment Is Inferior

  “Most of what passes for legitimate entertainment is inferior or 
foolish and only caters to or exploits people's weaknesses. Avoid being one of 
the mob who indulges in such pastimes. Your life is too short and you have 
important things to do. Be discriminating about what images and ideas you 
permit into your mind. If you yourself don't choose what thoughts and images 
you expose yourself to, someone else will, and their motives may not be the 
highest. It is the easiest thing in the world to slide imperceptibly into 
vulgarity. But there's no need for that to happen if you determine not to waste 
your time and attention on mindless pap.”
