What I'm saying is that I just hope L. Buckingham doesn't have too many distractions at home to stifle and slow down FUTURE creativity.

Writing is a lonely, ergonomically painful job, one that requires total concentration on the subject mattter. To write well, one must be intense, which can be debilitating to the brain. It takes a great deal of self-discipline not to allow such people to pull you off course. - from "Getting What You Want" by Robert J. Ringer

In his classic novel, East of Eden, John Steinbeck emphasized the connection between working alone and creativity when he explained, "Our species is the only creative species, and it has only one creative instrument, the individual mind and spirit of man. Nothing was ever created by two men. There are no good collaborations, whether in music, in art, in poetry, in mathematics, in philosophy. Once the miracle of creation has taken place, the group can build and extend it, but the group never invents anything. The preciousness lies in the lonely mind of a man."

Lennon and McCartney don't count. They wrote their best stuff separately, just credited it to each other. Even L. Buckingham says there are 'John' songs and 'Paul' songs.
