There are a few benefits to tracking work time but the main benefits boil down to transparency and reporting.

Schwartz explains that as humans we have four different types of energies to manage every day:

  • Your physical energy – how healthy are you? (We've written about that part before)
  • Your emotional energy – how happy are you?
  • Your mental energy – how well can you focus on something?
  • Your spiritual energy – why are you doing all of this? What is your purpose?


As humans, we are distinctly different from machines. At the core, this means that machines move linearly and humans move cyclically.

Productivity / Energy

How long the average person works every day has little to do with how efficient or productive. How many hours we work every day is barely important in today's creative economy. “Manage your energy, not your time.”

8 hour work days

Why a Typical Work Day is Eight Hours Long

In the late 18th century, when companies started to maximize the output of their factories, getting to running them 24/7 was key. To make things more efficient, people had to work more. In fact, 10-16 hour days were the norm.

These incredibly long work days weren't sustainable and soon a brave man called Robert Owen started a campaign to have people work no more than 8 hours per day. His slogan was “Eight hours labour, eight hours recreation, eight hours rest.”

One of the first businesses to implement this was the Ford Motor Company, in 1914, which not only cut the standard work day to eight hours, but also doubled their worker's pay in the process. To the shock of many industries, this resulted in Ford's productivity off of these same workers, but with fewer hours, actually increasing significantly and Ford's profit margins doubled within two years. This encouraged other companies to adopt the shorter, eight hour work day as a standard for their employees.

The reason we work 8 hours a day, isn't scientific or much thought out. It's purely a century old norm for running factories most efficiently.
