Relearning to tie your shoes is a powerful metaphore for retraining other habitual view points and behaviors.
It has taken me about 3 months to learn the new and improved way to tie my shoes. Each day I have had to deliberately and concisously work at getting it right. Now it is farily habitual with little thought needed to get it right.
This has been a powerful metaphore for me in working on other things that are habitual. For example, reactions in human interactions stem directly from habits of how I view the other person. A better view leads to better interactions and more postive results.
In the heat of a conversation or interaction with someone, the reactions are so fast that they are difficult to conciously catch in time to make a difference. However, if I conciously choose beforehand to have a better view of a person, it can become habitual and have a great impact on relations.
Some of these habits of viewing people in relationships go as far back as learning to tie ones shoes or even to a younger age.
Since it takes presistence to accomplish a change of habit, having a strong sense of focus and conviction that the idea is a good one helps a person stick to it.
