This is where LL for people of average height has its merits. It's one thing to go from very short to still pretty short, but less so. You won't become a stud though, and if that's not what you want, then great. You'll still get social benefits. But you'll still be left in a position in which, pheasibly, you could often still feel unhappy with your height, even after LL.
It's undeniable, however, that social benefits of going from "average" or having an "ok" height to having what society generally views as the "perfect heights" or ideal range which is (6'0ish-6'4ish) are tremendous, because, at this point, you actually manage to conquer height neurosis in that you get to a point at which there is literally absolutely no social need, advantage, or use for more height. Basically, unless you have a mental problem that makes you want to be as tall as physically possible, doing LL at average height (given that you have true height neurosis) will get you to a point at which you'll never have a reason to desire more height ever again. After living with height neurosis for years, that's a pretty sweet place to be if you ask me.
