The only flaw is that you are flawless. 

You are flawless with the bruises and cuts that mar your skin.

You are flawless with your chipped nail polish and lopsided glasses.

You are flawless in that you are flawed in ever way. 

There is no such thing as perfection, so why strive for it?

Strive to be the best you that is possible.

The only flaw is that I am flawless.

I am flawless with my retainer in and my glasses on.

I am flawless as I stand on the scale twentyfive pounds overweight. 

I am flawless because I do not care what you think about me.

I am flawed, and that makes me flawless.
