Sitting through a timeshare seminar for a free lunch isn’t the best use of our time when we think about all the other things we could be doing.
Signing up for Facebook seems like it costs nothing when you sign up until you realize how many hours are spent wasting our time.
Netflix is eight bucks per month but could be 100 plus hours of your attention after.
Cost is more than just price. It is the time spent deciding on a purchase or the attention it steals after. There’s maintenance. There is an opportunity (if I spend money here, I can’t spend it somewhere else). Keep in mind a dollar also represents your time too.
