Simplify your life. Example: Cleaning products. Find 1-2 products that clean almost everything safely. Don't buy a product for every type of cleaning.
You don't need to own every "cool" thing, or the latest trend. You are wasting money, it becomes clutter quickly, and you have to expend time & money later to get it out of your life, and it eventually goes to the landfill.
Less crap, fewer expenses = more happiness and time.
