A wise woman once said, "nobody's perfect." Love her or hate her, wise or not, Miley Cyrus speaks some truth. Nobody is perfect; we all have flaws, but that's what makes us all unique and beautiful.
You put the U in Unique
When it comes to our flaws and imperfections, we have several options: learn to accept them, or constantly try and "fix" what's "wrong." I've gone down the latter path, and so I can say from experience it's just not worth the time to constantly try and be perfect. If everyone was perfect, the world would be so boring. There wouldn't be diversity or a world of personality.
