It takes a lot of practice to be good…even spontaneous.
Example?
Flying cats and furniture and water and Salvador Dali.
Life Magazine shared the famous surreal motion photo in the late 40’s.
A “spontaneous” work of art that took 28 takes, throwing cats, a chair held up by an assistant and furniture held by wires (and air brushed out).
“Everything is practice”.  
Thank Pele for that quote.
