This isn't the case at all. WAV no longer writes poetry, and no longer travels; he has learned his 17 E. Trads, and 17 E. Hymns and has no intention of learning any more; these, along with 17 self-penned Chants form his entire performance repertoire. At singarounds he very carefully performs of his own chants and, if he gets another, he'll sing an E. Trad (showing us where his priorities lie). Basically, he is on a repeat cycle of endless repetition of his Life's Work & the promotion of same - no new songs, no new thoughts, no new insights, no chance of ever changing his mind because he has reached his CONCLUSIONS.
