"You know, I hate to give advice because my life has been so odd that almost nothing that's happened to me can apply"

In this quote, William Joyce reveals his hesitation to provide suggestions due to the uncommon experiences he has had in his life. He thinks that his life has actually been so special and unusual that the lessons he has actually found out might not apply to others. This could be interpreted as a sense of humbleness, as Joyce acknowledges that his life may not be relatable to others and for that reason his suggestions may not be useful. It could also recommend a sense of self-awareness, as Joyce acknowledges that his experiences might not be universal and for that reason his advice may not be generally suitable. In general, this quote highlights the value of acknowledging the individuality of everyone's life and experiences.
