“The E-Myth” by Gerber talks about working ON the business while working IN the business. You need to spend some time off the clock where you are not bounded by the demands of the moment. Those times are when you are visited by moments of clarity.
Long walks, runs, hikes, bike rides, golf and other time consuming physical activities not only provide these moments but they offer considerable health benefits.
Hobbies like gardening, woodworking, fishing also provide time out of mind opportunities.
The important thing about this is there is never enough time for this. You have to plan it like another activity and make sure it get’s on the calendar.
Oh, and leave the cell phone at home!
