The author, Cal Newport, says that “in a business setting, without clear feedback on the impact of various behaviors to the bottom line, we will tend toward behaviors that are easiest at the moment.” In other words, when you don’t have systems for productive activities, you will easily give in to distractions. So always measure your progress in order to become productive and successful.
Understand what a feedback system is.
A feedback system in your work informs you about the progress you’re making.
Create your feedback system and measure your progress.
Create your own feedback system by tracking the output of your work. Use a concrete number of productive hours, sales, money, etc.
