Manche Menschen sind sich aller Dinge sicherer als ich mir einer einzigen Sache. Robert Rubin - Susan Cain

Though shyness per se was unacceptable, reserve was a mark of good breeding.

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 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, 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 multi-tasking, 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.
