You do want to know which activities produce the best results. Write down the few key activities that you do each month. Keep track of what you actually do in those key activities every day, and then look to see if there is a connection between any of the activities and the actual results you achieved that month.
This can help you to determine what to keep the same and what to change as you move forward.
However, don’t track so many activities that you are spending most of your time living in the rear view mirror. The idea is to drive the car forward effectively and efficiently. You need some data points to do that well, but you don’t need to stop the car permanently to see where you’ve been.
