Foolish things if they are fools.
Sensible things if they are wise.
Frustration is one of those things which can precipitate foolishness or ameliorate a positive attitude. It's something wich probably allows no middle ground, you either move down or up.
Sometimes it participates creative activity. There's something internally brewing that seeks expression.
Yesterday I 'heard' part of a song in my consciousness that I have never heard before. I went outside to do some snowblowing and when I came back in I had forgotten it. Perhaps that was part of the unconscious frustration. Then I woke up early this morning and started hearing it again.
