“Do you want to be known for your writing, or for your swift email responses?” Whether you are a busy student or full-fledged academic, a start-up entrepreneur or the CEO of a Fortune 500 firm, it is essential to “just say no” to daily distractions like TV, social media, email, and other time-sucking activities. (Or at least cut down on these soul-destroying time thieves.) Or in the words of the late great Steve Jobs: “People think focus means saying yes to the thing you’ve got to focus on. But that’s not what it means at all. It means saying no to the hundred other good ideas that there are. You have to pick carefully. I’m actually as proud of the things we haven’t done as the things I have done. Innovation is saying no to 1,000 things.” Additional thoughts on the virtues of saying “no” are available here.

Efficiency.
