It's really very simple.
Have a good look at your body.
Observe that it is actually covered in skin.
Repeat these words - Wow! I am skinny.
Congratulations! You are skinny.
And most importantly, remember to be kind to yourself, and love the skin you are in.
It is what's inside that's important, the rest is window dressing.
Fat. Thin. Love the skin you're in.
Do you love yourself?
If not, why?
You can't expect others to love you, if you don't love yourself.
Love! Love! Love!
