When all else fails, go for the ego.
The quote "When all else fails, go for the ego" from Val McDermid's book "Crack Down" suggests that in challenging situations, appealing to someone's sense of self-importance may be an effective strategy. This implies that individuals often respond to their egos, and understanding this can be a tool for navigating conflicts or manipulations. It highlights the significance of recognizing psychological triggers when trying to influence others.
