Well, interestingly they can either complement each other or antagonize each other. Think of your shopping patterns. Do you shop for sport or out of necessity? Do you do only when necessary?
The more you shop the more there is to do. If you use the stores as a past time, hobby or distraction then you are in danger of letting it take over your to do time. Let’s face it, the more you shop the more you buy. Aside from the financial irresponsibility of this there is the stuff issue. If your house is not in reasonable order for you to easily and quickly use or put away what you have bought then you are really not helping yourself.
There is also the concern of maintaining what you buy which robs you of living time.
If you buy before you tidy, measure, organize, purge you are risking the chance of not buying the right things that fit in your house, décor, shelf space etc. Decide what you need for the space first so you can buy appropriately. Much more satisfying.
Another way of looking at this – looking at your life objectively, do you want a life that consists primarily of shopping for things that you want but don’t need or do you want a life that is busy because you are doing? I know what my answer is. That is not to say I am always living a balanced life in this respect but it does mean that I am aware and therefore continually re-evaluating my choices.
