This made me laugh. I guess you could take it a couple of ways..
One being that if you are an orange (an endomorph), you're barking up the wrong tree if you think you can look like a carrot (an ectomorph) ... which is true.. you're built the way your built. Everyone's version of healthy looks different remember :)
Another, more positive message I choose to take from this..
It's mental. Goals. You set them. You picture them. You work at them. You get there. You motivate everyone around you. But most of all, you see what you, yourself can do. And it feels Gooooood.
