There is something to that old saying that hate injures the hater, not the hated.
There is no substitute for hard work.
-- Thomas Alva Edison
Intimate or drastic elements in the work of others are untouchable and should not be commented upon even in their absence. Private conflicts, quarrels, sentiments, animosities are unavoidable in any human group. It is our duty towards creation to keep these in check in so far as they might deform and wreck the work process.
