Everyone enjoys the taste of free. Open bar at the reception, someone else’s birthday cake, dinner at Granma’s house, small toys buried in a krackerjax box, are all improved by the idea that they are free.
When I was seven years old I discovered that I could read my favorite comics in just a few moments right on the the news rack at the corner store, which was helpful because I was rarely able to buy them.
Now days I have come to believe that most things involve a trade of some kind. What do I want? What does it cost? How much time will I spend? Will it be worth the trade?
