There's zero correlation between being the best talker and having the best ideas. - Susan Cain

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.

According to Free Trait Theory, we are born and culturally endowed with certain personality traits — introversion, for example — but we can and do act out of character in the service of “core personal projects.”
In other words, introverts are capable of acting like extroverts for the sake of work they consider important, people they love, or anything they value highly. Free Trait Theory explains why an introvert might throw his extroverted wife a surprise party or join the PTA at his daughter’s school. It explains how it’s possible for an extroverted scientist to behave with reserve in her laboratory, for an agreeable person to act hard-nosed during a business negotiation, and for a cantankerous uncle to treat his niece tenderly when he takes her out for ice cream.

It can be hard for extroverts to understand how badly introverts need to recharge at the end of a busy day. We all empathize with a sleep-deprived mate who comes home from work too tired to talk, but it’s harder to grasp that social overstimulation can be just as exhausting.
