22강 1 The people who came before you invented science because your natural way of understanding and explaining what you experience is terrible. When you have zero evidence, every assumption is basically equal. You prefer to see causes rather than effects, signals in the noise, patterns in the randomness. You prefer easy‑to‑understand stories, and thus turn everything in life into a narrative so ..

12강 1 Clutter beats us up psychologically and physically. It clouds our minds, making it difficult to access what truly matters in our lives. According to Ab Jackson, a fellow organizer, “Are you a person that buys things that you don’t need, with money that you don’t have, to impress people that you don’t even like?” Sound familiar? How reassuring would it be to get organized in a way that not ..

11강 1 To many people, having a goal is synonymous with commitment, and commitment to a goal—in turn—is nearly synonymous with success. Legendary boxer Muhammad Ali once remarked, “I hated every minute of training but I said, ‘Don’t quit. Suffer now and live the rest of your life as a champion.’” And there you have it—the clear sentiment that doubling down on goals is more likely to lead to succe..

10강 1 One of the great risks of writing is that even the simplest of choices regarding wording or punctuation can sometimes prejudice your audience against you in ways that may seem unfair. For example, look again at the old grammar rule forbidding the splitting of infinitives. After decades of telling students to never split an infinitive (something just done in this sentence), most composition..

9강 1 Scientists hope to someday establish beyond a doubt that aging and all the nefarious things that go with it can be indefinitely postponed simply by reducing the amount of food and calories we consume. Take note that in the prevention of Alzheimer’s disease, maintaining an ideal weight may not be enough. Studies have shown that the risk of Alzheimer’s disease is more closely linked to calori..

6강 1 In the 1990s the Internet became the newest entrant in the baby advice field. Major manufacturers of baby equipment as well as the neighbor down the street set up Web sites to help parents care for their babies. Chat rooms brought mothers from all around the country together online to discuss, question, and support each other. The Internet meant that the speed of information available to mo..

5강 1 If you have become much less active, spending a lot of time alone focused on feeling depressed, think about activities that engage your attention and that require a moderate level of concentration and effort. Driving, for example, is probably not ideal, because it is such an automatic behavioral sequence for most people that it siphons off only a small amount of attention. Something like st..

4강 1 Opera is conventional. Nobody sings all the time in the real world. Nobody has an orchestra that begins to play whenever he feels emotional. Conventions are of course necessary in the theater, and even more so in opera. We like conventions, provided that we understand, accept, and desire them. Conventions are simply the result of participants’ agreeing on the rules, of simplifying a complex..

3강 1 If you find it difficult to stay wise-minded when your teen is rude, it’s no surprise. The deck is stacked against you because of several inescapable facts of normal teenage behavior. For one thing, teens often try to pick a fight. That’s because, in the chaos and uncertainty of adolescence, parents are a secure base—sort of like the eye of a storm. Teens want to discharge the garbage of th..

1강 1 It will never be possible to establish the origins of human music with any certainty; however, it seems probable that music developed from the prosodic exchanges between mother and infant which foster the bond between them. From this, it became a form of communication between adult human beings. As the capacity for speech and conceptual thought developed, music became less important as a wa..

2강 1 Your comfort zone is like an invisible barrier around you, inside which if you stay, you feel comfortable. Your comfort zone and your confidence are linked together. Step outside it and you feel uncomfortable and fearful. However, your comfort zone is not fixed. If you constantly stay within your comfort zone it shrinks, filling you with fear of what is outside it, and then your confidence ..

20강 1 For over a million years humans lived in small, mobile groups gathering their food from the wild and hunting animals. When resources permitted, they came together in larger groups and occasionally, when they could rely on particularly rich sources of food, they became semi‑sedentary. Then, in a relatively short period of time after the end of the last ice age, about 10,000 BCE, this stable..

21강 1 One possible disaster resulting from warmer temperatures in northern areas is a potential tipping point associated with the Greenland ice sheet. The “Atlantic conveyor belt” consists of warm water moving up the eastern coast of North America as the Gulf Stream and then sinking 10,000 feet near Greenland and moving back to the equator, where it warms and rises again. Large amounts of freshw..
