Productivity is a key for modern “success”, but not a key for a quality. This is simply not true. You are using geniuses like Picasso as example to push an untrue statement. There are many different approaches, and there were many geniuses who produced very little number of masterpieces. However, if you are speaking about the modern monetary success, then you are totally right, and I’m glad you’ve used Thomas Edison as example, because he was stealing ideas from others very productively.
