The obsessive pursuit of perfection can destroy effectiveness. How easy would it be, continuously review, rewrite, redo a project. Keep revolving within this loop until its perfect, or we die. I would expect that giving into this loop, perfection would only be achieved well after the project’s usefulness was long past.
Now, we need to keep mind for quality. Try to make whatever we’re creating as effective as possible. Yet, something is better than nothing.
Deliver the best you can. Fix, with diligence and haste any material mistakes, smile about the non-material. Be proud of your work, and the problems it solves.
