Prudence, when is it in the way?

The young do not know enough to be prudent, and so they attempt the impossible, and achieve it, generation after generation. - Pearl S. Buck

This abandonment (letting go of) of old ideas and other previously established behavior limits, puts the finger on my own way of dealing with the "should I do this?" or, if I decide to do it, when do I say the work is finished? (while creating a painting/improvizing/performing) of an artist/writer/musician. Here is a quote that suggests we should let prudence off the hook and let 'er rip, especially when it comes to listening or agreeing with what we hear:

Just as the highest and the lowest notes (on the musical scale) are equally inaudible, so perhaps, is the greatest sense and the greatest nonsense equally unintelligible. - Alan Watts

One of the best quotes I have heard that depicts how important music is in our lives is:

Music washes away from the soul
the dust of everyday life.
- Berthold Auerbach
