I then came across this little video where she describes her art and the significance of the MOMA piece for her at that career stage. In it she she quotes one of Leonard's gems about the "third act" of life. It's worth watching the whole 2:15 minutes to get the context, but the Leonard quote is at the 1:35 minute mark.
