I've had numerous bursts of enthusiasm for various products that have resulted in failed entrepreneurial endeavours. Making a fair priced, quality product available to others isn't enough - idiot consumers need song & dance sales pitches and they need everyone else to do their thinking for them by buying it before they do. In the end, it's always me that is the idiot for trying to service an idiot market with smart-people products.

Or, to put it another way, "The customer is always right ... and is usually stupid."
