Question: Is it true that failing equals success?
Answer: Failure is half of the success. Without failures, without the contrast we gain by failures we could not even measure if we were successful or not.
A child that keeps rebuilding a LEGO construct while constantly breaking, “mis-building” it could never learn properly how to build, and would never become a “master builder”.
Scientists need negative results, failures just as much as they need successful ones. The negative results are part of the scanning, mapping process, narrowing the path towards a most optimal, final goal.
