"I always believe in going hard at everything, whether it is Latin or mathematics, boxing or football, but at the same time I want to keep the sense of proportion. It is never worth while to absolutely exhaust one's self or to take big chances unless for an adequate object. I want you to keep in training the faculties which would make you, if the need arose, able to put your last ounce of pluck and strength into a contest. But I do not want you to squander these qualities."

Simplicity is the ultimate sophistication. It takes a lot of hard work to make something simple, to truly understand the underlying challenges and come up with elegant solutions. [...] It's not just minimalism or the absence of clutter. It involves digging through the depth of complexity. To be truly simple, you have to go really deep. [...] You have to deeply understand the essence of a product in order to be able to get rid of the parts that are not essential.
