Do you sometimes want to buy stuff even though you don't need it?
Meanwhile other important things seem too expensive and you're hesitant to pay?
I think almost everyone has these situations.
But I will tell you a trick that can help you influence your own opinion!
(assuming you already know which direction you need to influence it in)
Surely you've come across something in your past that is massively overpriced.
And occasionally you might encounter something that is underpriced.
These are important to remember, because you can use them for this trick!
So basically, when you feel an urge to buy something that you don't really need?
You should mentally compare it to something underpriced (within the same price range).
This will make it seem more expensive and help you avoid an unnecessary purchase.
Similarly, when you need to buy something important but it seems expensive?
You should compare it to something overpriced within the same price range.
This will make it seem relatively more valuable.
That's it! I hope this helps!
