Our difficulty accepting impermanence is the heart of human suffering. - Susan Cain

Highly sensitive people tend to be keen observers who look before they leap. They arrange their lives in ways that limit surprises. They're often sensitive to sights, sounds, smells, pain, coffee. They have difficulty when being observed (at work, say, or performing at a music recital) or judged for general worthiness (dating, job interviews). But there are new insights. The highly sensitive tend to be philosophical or spiritual in their orientation, rather than materialistic or hedonistic. They dislike small talk. They often describe themselves as creative or intuitive (just as Aron's husband had described her). They dream vividly, and can often recall their dreams the next day. They love music, nature, art. They feel exceptionally strong emotions -sometimes acute bouts of joy, but also sorrow, melancholy, and fear. Highly sensitive people also process information about their environments -both physical and emotional -unusually deeply. They tend to notice subtleties that others miss - another person's shift in mood, say, or a lightbulb burning a touch too brightly.

Consider that the simplest social interactions between two people requires performing an astonishing array of tasks: interpreting what the other person is saying; reading body language and facial expressions; smoothly taking turns talking and listening; responding to what the other person said; assessing whether you're being understood; determining whether you're well received, and, if not, figuring out how to improve or remove yourself from the situation. Think of what it takes to juggle all this at once! And that's just a one-to-one conversation. Now imagine the multitasking required in a group setting like a dinner party.

Another study, of 38,000 knowledge workers across different sectors, found that the simple act of being interrupted is one of the biggest barriers to productivity. Even multitasking, that prized feat of modern-day office warriors, turns out to be a myth.
