Work Accomplished = Time Spent x Intensity

The Straight-A Method

In the early 2000’s, I was obsessed with study habits. The obsession began with my interest in performing well at Dartmouth, then eventually evolved into a (surprisingly popular) book.

Something I uncovered during this period is that high performing undergraduates, as a general rule, seem to internalize the following formula:

Work Accomplished = Time Spent x Intensity

This formula helps explain why some students can spend all night in the library and still struggle, while others never seem to crack a book but continually bust the curve. The time you spend “studying” is meaningless outside of the context of intensity. A small number of highly intense hours, for example, can potentially produce more results than a night of low-intensity highlighting.

(This is how I avoided all-nighters, for example, during my three year stretch of 4.0’s as an undergraduate.)

From Campus to Corporation

I’m mentioning this phenomenon because of the following observation:

The above formula applies to most cognitively demanding tasks.

In other words, intensity affects the productivity of a knowledge worker as much as it helps the GPA of a college student.

Deep Habits: Using Milestones to Get Unstuck

In Search of Productive Simplicity

Last week, I described a kink in my project productivity systems. I was oscillating, somewhat haphazardly, between two different strategies, tracking hours (e.g., when the work is open-ended), and pursuing milestones (when the work is known and I need to hustle).

This felt too complicated, so I asked for your thoughts and you responded with over thirty suggestions.

A lot of your advice seemed to fall into the category of “different work requires different tools, switch as needed.”

This is probably good counsel.

But it still nagged at my preference for simplicity in such matters (which, as a theoretical computer scientist, I of course measure in terms of Kolmogorov complexity).

Deep Habits: Should You Track Hours or Milestones?

Meaningful Metrics

Some of you have been requesting to hear more about my own struggles to live deeply in a distracted world. In this spirit, I want discuss strategies for completing important but non-urgent projects. In my experience, there are two useful things to track with respect to this type of work:

  1. Specific milestones: for example, the number of book chapters completed or mathematical results proved.
  2. Hours spent working deeply toward milestones: for example, you can keep a tally of the hours spent writing or working without distraction on an important proof.

In my own work life, I find myself oscillating between these two types of metrics somewhat erratically, and I’m not sure why.
