I agree that you don’t need to be a perfectionist to create beautiful things, but I think it’s fair to say that all three of those men you mentioned were perfectionists in their own way.
Jobs was willing to fail, but it would never be due to a lack of willingness to follow through on his vision. The NeXTcube failed, but not without Jobs putting together an unreasonably dimensional product.
With Picasso, perfectionism didn’t mean creating a perfect copy of the world around him. It meant creating a perfect copy of the world as he saw it. Realism may be more accurate, but that doesn’t mean it’s more perfect.
Still, I agree with the main point of the article that the pursuit of perfection can be as dangerous as it is helpful. Perfection can get in the way of one's ability to follow through on something imperfect, and all three of the men you mentioned nearly went mad at some point in their respective lives.
