My Weekly Learnings #42 (09.01.22 – 15.01.22)

Amidst all the content I consume every week, through this weekly series of ‘My Weekly Learnings’, sharing highlights of content pieces that caught my eye and provided more value than I could imagine.

(P.S. Every Sunday, I share a list of what to read, listen to, and watch, in my weekly series, The Last 7 Days. You can check out the editions here).

1. Long hours spent staring at screens underworks panoramic vision, predisposing us towards flight-or-fight sympathetic nervous system activity.

This is another reason that prolonged screen time can leave us feeling fatigued; the nervous system has been using a lot of resources to keep us alert, which can leave us feeling wired and tired and the eyes feeling exhausted. ⠀

The eyes are doing a lot of work when we engage in prolonged screen time behaviors. We aren’t aware of this work, but it is still physically (and mentally) fatiguing. This work involves blink and near triad reflexes and everything needed for high visual acuity foveal vision. It also involves dealing with glare, making sense of confusing focus and depth cues, and greater visual workloads. But that’s not all; screens also place extra demands on eye defenses from blue light. [Neurohacker]

2. “The longer you’re a teacher, the less you remember what it is like to be a student.

The longer you’re a doctor, the less you remember what it is like to be a patient.

The longer you’re a coach, the less you remember what it is like to be a player.

Change positions. A new perspective can improve your old methods.” [James Clear]

3. Writer David Chapman on how to improve your thinking:

“Learn from fields very different from your own. They each have ways of thinking that can be useful at surprising times. Just learning to think like an anthropologist, a psychologist, and a philosopher will beneficially stretch your mind.”

4. A song becomes catchy if a few words are repeated enough.

A lie starts becoming truth if it’s repeated enough.

A faith becomes blind if rituals are repeated enough.

We accept everything as safe & normal if an experience is repeated enough.

Repetition is the human kryptonite. [Kunal Shah]

5. What you do on the bad days matters more than the good days.

What you do when you don’t feel like it — when you’re not motivated, when everything seems hard — matters more to the ultimate outcome than what you do when you’re motivated and it is easy.

Maintain the momentum. [Shane Parrish]
