Patricia Ryan Madson has written the book Improv Wisdom . She gets it (improvisation) and shares her years of experience with the art of improvisation in a pointed composition which even I can relate to. Furthermore, she applies improvisation to life; while I am currently still adapting it to the kitchen. Funny point is her approach to improvisation closely mirrors our approach in the kitchen; yes we do speak of culinary improvisation though it is validating to read someone else's well developed principles.
One quote from the book which ties into our everyday is "We are all borrowing heavily from the labors and efforts of others. But it takes another lens to view it this way--to see these amazing loans from the universe." In our constant search for creativity and ideas we often forget how much borrowing exists. It is the acknowledgment and honest acceptance of this borrowing which allows us to move forward, creating and expanding our horizons.
