The challenge of a long term change in a habit or behavior can be quite daunting. I have found that it is reasonable to alter the behavior for a one week period and test the water without a complete leap.. Treat it as aone week trial with a money back guarantee. If the desired change is more exercise, or cessation of smoking, or more time to read do it for a one week period, Committing to a permanent change may be too difficult to take on with a final decision..A week is a period where if the decision is serious it will become more firm, and could lead to significant change. Climbing the mountain may be beyond the scope of our will but a week passes quite fast.
