We are accustomed to understanding evolution as something that occurs only in nature, that is, as a biological phenomenon. But this is not the case, and it was biologists who defined the process in which a series of failures leads to the emergence of correct solutions: evolution. Despite our instinctive belief that important issues require thoughtful expert decision, very complex things most often come to light as a result of applying a very simple, old-fashioned method - trial and error. In today's complex, ever-changing world, making mistakes is absolutely necessary. And it does not matter whether we make mistakes knowingly or out of ignorance. If you do not give up and constantly try new things, success is guaranteed.
