Start putting a value on items you see in a store in terms of hours of your life it will take you to earn enough of your nation’s currency to purchase that item.
For example…Those $200 pair of shoes will take me 8 hours of my life that I can never get back to purchase. If the shoe enables you to work more efficiently subsequently enabling you to earn more, it could be worth the purchase. If the shoe cannot enhance your productivity, or efficiency you may choose to not purchase the shoe.
My son started a small business and now he values his time differently. I heard him tell his sister that he’s not spending his money on something she asked to him to buy because it will take him “X” amount of time to earn that money back. On his own my son made a choice about how much his time is worth and realized his time was worth more than a material item. His behavior (time preference) changed because of his experiences.
Give your children the necessary experiences to change their behavior. Whatever that means for you (not telling anyone how to parent). This must be an intentional effort on our part as parents.
Hope this inspires someone.
Peace & Love
