Pay Too Much
People buy the cheapest stuff so they can afford to buy more with their money. But because more expensive stuff often provides more value in the long term, paying more means you can actually buy more. When you buy a John Deer or a Snapper you don’t have to replace it every other year like that random wally world lawnmower.
Getting a purchase right the first time by not skimping also means you get to be happier with what you have for longer. Rarely will you regret spending a little more for something you will value and use.
