In Steven Covey's book "The 7 Habits of Highly Effective People", habit number 7 is "Sharpen the Saw". This is a metaphor for taking time to rest, to learn, to prepare your tools, to plan... before diving into business.
Productive people take time to sharpen the saw before using the saw. Do you sharpen your tools? Do you take time to put yourself in a good state of mind for high performance?
