The notion that producing every result perfectly is necessary to be successful is gaining credence. People often fall for the pitfalls of spending too much effort perfecting something of lower importance while leaving less time for crucial matters.
Perfection has its place, but with attention and willpower being a scarce resource, it is valuable that you make a deliberate choice not to perfect many. Learning the art to perfect only things that matter holistically goes a long way to keep your effort productive.
Perfect what needs to be perfected, and leave the rest imperfect.
