Here's what's wrong this quote. Being perfect doesn't mean you have to look flawless in the physical aspect. Yes, I'm not perfect. That doesn't make me ugly. Your beautiful heart makes you perfectly imperfect. Not having a flatter stomach, etc.
My father taught me to be nice first because you can always be mean later. But once you've been mean to someone, they won't believe the nice anymore. So, be nice; be nice until it's time to stop being nice, then destroy them.
Where you are today is no accident. God is using the situation you are in right now to shape you & prepare you for the place he wants to bring you into tomorrow. Trust him with his plan even if you don't understand it.
