In your personal life, when attending to business or working on side
projects, how often do you spend 8 consecutive hours in front of a
computer? It doesn’t make sense because we lose the ability to
concentrate effectively within a few hours.Everyone goes through
alternating periods of high and low mental acuity. There are days
when I work on personal projects for well over 8 hours, but the time
is always divided into multiple sessions. I might spend a few hours
coding a design, a few hours writing, and a few hours reading feeds,
moderating comments, and responding to email.
I work this way because it aligns with my mental energy cycle. Any
more than 3 hours in front of a computer and my eyes start hurting
and I become restless. I lose the ability to do my best work.
Instead of forcing myself to continue, I switch to an activity that
allows my mind to recharge. These breaks maximize productivity by
eliminating down periods. It’s counter productive to force work when
the mental energy isn’t there.
The Problem with an 8 Hour Work Day
A continuous 8 hour work day is a relic of the past. It makes sense
for physical labor and manufacturing work, but with information
workers it doesn’t account for the mental energy cycle. The ability
of a factory worker to think analytically is irrelevant, he’s either
cranking widgets or he isn’t.
In the case of the modern information worker, nearly all tasks
involve creative or strategic thinking. The way someone answers an
email or interprets a piece of information can differ drastically
depending on his or her energy level. Nobody does their best work
5:30 in the afternoon after they’ve been sucking down coffee all day
to stay awake.
