All seven of the SEVEN LAWS OF THE MIND are excellent reminders to me of principles that I must continue to keep motivated to do so I can move forward. With that in mind, the Law of Practice seem to stand out in boldness to me. Perfect Practice Prevents Poor Performance. With practice of the correct things, not just knowledge of correct things.
As was pointed out in article 36 of the week 15 master key lesson, knowledge does not apply itself. Often our actions are not governed by knowledge but by custom, precedent and habit. Therefore, bringing us to the awareness as Og Mandino pointed out, we can blindly follow the customs, precedents, and habits of others and be greatly limited or impaired in our own reasoning ability and insight. While much can be learned by observing the actions of others, we owe it to ourselves to qualify any information or action by inductive reasoning (week 11 master key lesson) and our own principles and beliefs.
