The movie struck a surprise chord with me though. As a fat person, you may have been referred to as an elephant. I have. Maybe you've been called Dumbo, hippo, gigantic, huge or giant. Did it make you feel like a freak? The fattest person in the world, come one come all? I know acceptance isn't so easy as phrases like "own it" make it seem. Perhaps you could try "don't be afraid to refer to it" instead. Refer to your fatness, your inspiration.. your expression.
If you just need someone to tell you that you may, in fact, be your own person and do with that what you wish you have my blessing. Be a clown, be an elephant, be the lady who rides the horse standing up.. just don't be afraid to refer to it.
Be big, be generous and be JUMBO!
