Was just told about the Pablo Picasso story creating a drawing for a fan in merely minutes and then asking for the equivalent of $500,000 in dollars today. She was offended and said but why would I ever pay that much when it took you only minutes to do? The answer was that it's not the time it takes to do something it's the skills behind being able to do so and that is what you pay for said the Spanish Artist. It took me 30 years to refine my craft and that is what you are paying for.
This is no difference than the plumber who comes to your house to fix your Air Conditioner and takes a look at the machine, asks for a hammer, bangs the machine once and fixes the issue and asks for $1000. Knowing how to use that hammer and the skills behind your craft are whats valuable.
