Shyness is the fear of social disapproval or humiliation, while introversion is a preference for environments that are not overstimulating. Shyness is inherently painful; introversion is not.

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.

Yet today we make room for a remarkably narrow range of personality styles. We’re told that to be great is to be bold, to be happy is to be sociable.

If you’re an introvert, find your flow by using your gifts. You have the power of persistence, the tenacity to solve complex problems, and the clear-sightedness to avoid pitfalls that trip others up. You enjoy relative freedom from the temptations of superficial prizes like money and status. Indeed, your biggest challenge may be to fully harness your strengths. You may be so busy trying to appear like a zestful, reward-sensitive extrovert that you undervalue your own talents, or feel underestimated by those around you. But when you’re focused on a project that you care about, you probably find that your energy is boundless.
So stay true to your own nature. If you like to do things in a slow and steady way, don’t let others make you feel as if you have to race. If you enjoy depth, don’t force yourself to seek breadth. If you prefer single-tasking to multitasking, stick to your guns. Being relatively unmoved by rewards gives you the incalculable power to go your own way. It’s up to you to use that independence to good effect.
