Think about the money you need to spend. Calculate it in terms of beef. You might want to buy a bag of candy for $4. Three bags of that is a piece of steak. That’s one meal. That’s over half of what you would spend on food. If you buy Starbucks for $10, that’s almost a piece of steak. And you spent it on a unnecessary cup of drink that you’ll finish in 30 minutes.
When you think you need to eat some stupid stuff, ask yourself why you want it. Always tell yourself no.
