"There comes a point where you have to throw yourself off a cliff and learn how to fly. Not so much for what you're going to get when you risk yourself in that particular way, but because of who you're going to become."
I'd choose getting 4~5 more inches to my height. Screw muscles. but if I HAD to choose, i'd probably pick arms.
my back and shoulders are already pretty good from swimming, so i dont really need to worry about that
