“We fail to build slack because we focus on what must be done now and do not think enough about all the things that can arise in the future. [...] What should you do?

We would be giving you back all that mental bandwidth that you currently use to fret, worry, and juggle these arrangements. We'd be taking a cognitive load off. As we've seen, this would help your executive control, your self-control more broadly, even your parenting. It would increase your general cognitive capacity, your ability to focus, the quality of your work, or whatever else you chose to turn your mind to. From this perspective, help with child care is much more than that. It is a way to build human capital of the deepest kind: it creates bandwidth.”

“A standard impulse when there is a lot to do is to pack tightly-- as tightly as possible, to fit everything in. And when you are not tightly packed, there's a feeling that perhaps you are not doing enough...You have undervalued slack. The slightest glitch imposes an obligation you can no longer afford, and borrowing from tomorrow's budget comes at high interest.”
