I do envy other guys, like guys with broad, muscular shoulders and chests, lean guys, guys with good facial hair, guys who can snowboard, mountain bike, rock climb, and even guys with good cars - whether they're trans or cisgender. But I don't let it make me feel dysphroic about myself, I use them as inspiration to shape my own body and life. I want a nice, muscular body - so I'll work out, exercise, and eat right until I'm satisfied and have reached my maximum fitness. I want a deeper voice and facial hair - so I'll take testosterone. I want to get active and participate in some extreme sports, so I'll go to a wall climbing place and learn or hit the rough terrain with my bike.
I may never look like this guy or that guy but I'll look like me at my full potential and that's all I could ever want.
