A friend and colleague of mine Barbara Scott recently sent me the following quote by Jim Jarmusch.
Nothing is original. Steal from anywhere that resonates with inspiration or fuels your imagination. Devour old films, new films, music, books, paintings, photographs, poems, dreams, random conversations, architecture, bridges, street signs, trees, clouds,bodies of water, light and shadows. Select only things to steal from that speak directly to your soul. If you do this, your work (and theft) will be authentic. Authenticity is invaluable; originality is non-existent.
And don't bother concealing your thievery--celebrate it if you feel like it. In any case, always remember what Jean-Luc Godard said: 'It's not where you take things from--it's where you take them.'"
We are the sum of our experience bring ourselves to the co-creation. Even when we are working alone we are in collaboration with authors, teachers, friends and colleagues from our lives.
Take the things you learn. Try it out. Change it. Make it your own.
I learned improv from many wonderful improvisers as coaches and peers. Where I can I try to pass along the chain of attribution to help preserve the shared history and impart it to others.
