Forgetting has a cost.
Suppose you forgot an important paper at home, you have to pay the price for going back and retrieving it, not to mention the time wasted for going back and forth.
You need to remember. But remembering also has a cost.
You pay a price for the alarm clock you have on your headboard. You pay for that reminder app on your iPad. You pay for your organizer or planner.
Some people even pay some people to remember things for them. They're called coordinators.
So the question is, which is higher, forgetting cost or remembering cost? Forgetting cost, of course. You would rather pay for remembering cost than pay for forgetting cost, right?
Remembering cost is actually a cost incurred to prevent forgetting cost. You buy an alarm clock because you don't want to be late. The cost of being late can range from losing some cents from your paycheck to losing your own business. You invest in remembering cost because you don't want to pay for the higher forgetting cost.
One more thing, remembering cost is usually a one-time cost. You don't buy an alarm clock everyday. But if you get late everyday, you pay for the repercussions everday.
So, definitely, it is better to invest in remembering costs to prevent forgetting costs.
