With everything we buy, there are 3 costs...

The first 2 are well known; there's the cost of the money that we spend and the cost of the time we spent earning that money. 

But there's also a third cost that's rarely talked about - and far more important to know. 

And that is the 'Missed Opportunity Cost'. 

Because whenever we buy something, we simultaneously take away the ability to buy something else.

And that missed opportunity can be incredibly expensive.
