This is a great, simple summary that is easy to remember.
However, a fourth category may clarify our thinking. What about adding the category “live” as something we can do when you make money? This would make the four things – give, save, spend, and live. This may help us remember that some spending is the necessary stuff of life. Other spending is just something we have always thought would be cool to own. We all know that purchases can be broken into needs and wants. And it would probably take a long time (can someone say eternity?) for us all to agree that the same items belong in the same list. Nevertheless, this reminds those of us who are seeking to live a simplistic life that there are some forms of spending that are necessary and some spending (gasp) that we can live without.
Try prioritizing how you use money. And yes, the list IS in order of importance.
