For some, it is to make up for the fact that they were raised in poverty. They never owned anything during their childhood, so they want things now. For others, the need to possess goes far deeper into the fabric of their lives. Some buy possessions for other people, including children and grandchildren, because they want to be remembered and loved. Some busy parents surround their children with things in place of parental attendance and guidance.
Some people buy out of loneliness.
Some people impulse-buy to impress friends and fellow shoppers. Stop, all of you. Stop right now. Do not purchase another thing until you have examined your own reasons for possessing it. Stop purchasing unnecessary items for six months.
