“Trigonometry lets you use some known quantities about a triangle to determine its unknown quantities, we will interrupt ourselves right now because we can already hear you muttering, “Come on, when am I ever gonna use this?” Here is when you are going to use this: in navigation, astronomy, music, number theory, engineering, electronics, physics, architecture, optics, statistics, cartography, and more. You already need it just to build a proper sundial, hence the unofficial slogan of trigonometry: “Okay, fine, I guess this is actually pretty important after all.” Trigonometry deals only with right triangles (triangles with two edges that meet at 90 degrees, and we mark that angle with a little square), but since any non-right triangle can be divided into two right triangles (try it; it’s true), that’s not going to be a problem.”

“Wahai, wanita-wanita yang hingga usia tiga puluh, empat puluh, atau lebih dari itu, tapi belum juga menikah (mungkin kerana kekurangan fizikal, tidak ada kesempatan, atau tidak pernah 'terpilih' di dunia yang amat keterlaluan mencintai harta dan penampilan wajah.) Yakinlah, wanita-wanita solehah yang sendiri, namun tetap mengisi hidupnya dengan indah, bersedekah dan berkongsi, berbuat baik dan bersyukur. Kelak di hari akhir sungguh akan menjadi bidadari-bidadari syurga. Dan khabar baik itu pastilah benar, bidadari syurga parasnya cantik luar biasa.”

“When children earn stickers or candies by working as a team, they withhold their goodies from children who didn't help but share with children who did. This might not seem very friendly—it might even seem like behavior you should correct: sharing is caring after all—but from an evolutionary standpoint, it's mission critical.”

“Although we suffer from many of our ancestors' bad habits, they also evolved a motivational system that continues to reward us when we get it right. This is happiness.”

“The contents of our mind are a product of our genes, our environment, and our personal choice. Our genes nudge us in certain directions—sometimes this nudge might more aptly be described as a shove—but we make the decisions that determine the trajectory of our lives.”

“Unlike the West, the “true self” is not created over time but discovered7, which is why Daoist and Zen writings may refer to it as “original nature.” Our original nature is a primordial melody, and to hear it, one must silence all the extraneous noise.”

“53. The 9-mile-long river called Rio Celeste (“Celestial River”) in Costa Rica is a perfect metaphor for the harmonious interaction between the original self and the narrative self. While the original self carries the potential (aluminosilicate), it is in interaction with the narrative self that allows it to be realized.”

“A clear mirror reflects all things in the world, whether they are judged as “unpleasant,” or “beautiful.” “Unpleasant” things do not damage mirrors. A mirror does not cling to the images it reflects, once something is out of view, no trace is left behind.”

“To be spontaneous does not mean to simply express any urge and indulge every desire. That would be impulsivity. Impulsivity neglects complexity and context, whereas spontaneity considers them.”

“Rather than a linear evolutionary progression, the trajectory is like a spiral, the end eventually incorporates the beginning, though it also extends beyond it. One unlearns to learn, and by letting go we gain.”

“From another perspective, death is necessary to sustain the living. In our everyday lives, cells die; indeed, their death is necessary for life. Apoptosis, or selective cell death, is a developmental process that occurs throughout our lives especially in the initial stages. One of the primary risk factors of developing autism is the failure of apoptosis. This is also reflected psychologically; as we get older there are behaviors that must “die” before new psychological structures and behaviors can emerge. Alternatively, too much life can bring death. In adulthood, cells continue to proliferate, and when there is not the added component of death or apoptosis, cancer emerges.”
