Okay, so here's the longer, politically correct version. I didn't meant to denigrate myself...

One of my goals as I grow personally is to become more like you. I admire your bravery in mastering a skill set far outside the realm of what you were indoctrinated as a child to see as desirable or even acceptable. I would like to emulate that behavior.

In addition, I would like to make friends with my body and become strong and slim like you are.

Better wording?
