Do you often find yourself over-stimulated when out in the world and long for the comfort of home? Are you strongly affected by other people's moods? Do you consciously avoid violent films, TV shows or books? If so, you may be what Elaine Aron calls an HSP (highly sensitive person). And you're not alone - apparently, we make up 20% of the population! Her book is aimed at helping HSPs to survive in a competitive, demanding world where sensitivity is often viewed as a weakness.
