hate and pride belong to the same source

"[...] hate [...] pride [...]"

I think Bruce just forgot adding envy and fears into the same mixture, *and* to mix it well.

Pride comes before a fall, so does he really think it's Not Enough Fall?

(being a humble reader/developer/maintainer/manager who recognizes his envy, even if not hate,
all too often -- even if for completely weird reasons :)
