Performing means carrying out an action. I use the word performer to refer jointly to musicians, dancers, actors and all live artists. Their work is an action and not a physical piece and only if recorded will it leave a physical trace. The object can disappear, but the lived experience can’t. Possessions can increase and decrease throughout once life, but experiences only increase and increase and increase. Aiming our attention at this aspect of our life can be a secure investment in satisfaction.
