Failiure and Perseverance

Errors are a vital in the creation of a new idea. They are encountered countless times before a new invention is born. We've always been told about "trial and error," and how errors aren't as bad as they seem. Mistakes often lead to the birth of a new idea or invention. Simply by failing, you learn something new, and you build upon that failiure to build anew, and try again. Perseverance is key to trial and error. As Steven Johnson mentions in Where Good Ideas Come From ,errors are but learning opportunities, opening more doors to the adjacent possible. Promising inventors also experience errors. In fact, they experience more errors than a regular human being would. What makes them different is that they persevere through the pain of failiure, and learn from their mistakes. In my opinion, error and perseverance are the most important factors in the creation of a new idea, being that a new learning opportunity comes with every mistake. I might be wrong, of course; so I ask you, what is the most important factor in the creation of a new idea? Failiure? Curiosity, perhaps? Or is it something else?
