Everything is already perfect. And if you can accept that everything is already perfect, the imperfection is a part of the perfection. What's to worry about?
A perfect Judge will read each work of Wit
With the same spirit that its author writ:
Survey the Whole, nor seek slight faults to find
Where nature moves, and rapture warms the mind.
Even the clearest and most perfect circumstantial evidence is likely to be at fault, after all, and therefore ought to be received with great caution. Take the case of any pencil, sharpened by any woman; if you have witnesses, you will find she did it with a knife; but if you take simply the aspect of the pencil, you will say that she did it with her teeth.
And if there be any addition to knowledge, it is rather a new knowledge than a greater knowledge; rather a singularity in a desire of proposing something that was not knownat all beforethananimproving, anadvancing, a multiplying of former inceptions; and by that means, no knowledge comes to be perfect.
How can we say nobody's perfect if there is no perfect to compare to? Perfection implies that there really is a right and wrong way to be. And what type of perfection is the best type? Moral perfection? Aesthetic? Physiological? Mental?
The pursuit of perfection is frustrating and a waste of time, because nothing is ever perfect.
The pursuit of excellence is commendable and worthwhile. Therefore strive for excellence not perfection.
