Cost and value
One of my books took more than a year to write, ten hours a day. Another took three weeks. Both sell for the same price. The quicker one outsold the other 20 to 1.
A $200 bottle of wine costs almost exactly as much to make as a $35 bottle of wine.
The cost of something is largely irrelevant, people are paying attention to its value.
Your customers don’t care what it took for you to make something. They care about what it does for them.
