how you can turn failure into a stepping stone for success in marketing research.?

There are four types of failures we may encounter: we expected to find something and discovered a void, we sought something substantial but found it to be more malleable, we attempted to use a material that proved too rigid, and finally, when we searched for an empty vessel, it turned out to be occupied. Based on the type of failure, we can find ways to transform it into a form of utility: who placed what we did not expect to find, who benefits from such hardness, what could we fill it with if it were empty...? If we realize this, it's as if we were trying to sell a valid product to the wrong market. Sometimes it's a matter of redefining the target.
