Perfection: Flawless or whole?

Trying to perfect yourself is good.  That is, if you don't define perfection as "without flaw".

"Flawless" is an impossible to achieve standard. Worse, trying to avoid mistakes (oh no, flaws!) can prevent creativity.

The correct standard of perfection is "being whole".  Think of a circle.  All circles have flaws.  Get critical enough, look at them under a microscope and you'll find the flaws.  Be a circle, be whole, and let it be enough.

Also, be the size you need to be.  A bigger circle is not a better circle.
