In business, demand is invariably more important than supply. If demand doesn’t exist, supply is irrelevant. If demand exists, supply will eventuate.
I happened upon a quote from one of the greatest inventors / entrepreneurs in history Thomas Edison. Despite the simplicity of the idea, it’s very profound.
“I find out what the world needs, and then I proceed to invent it.”
This is some pretty good advice for any entrepreneur. It’s better to make what you can sell, than try to sell what you can make.
