Replying to Stiff as a board... agility and flow issues

I'm sure I'm probably going to get flack for this, but I gotta ask anyway since it's driving me nuts.

I notice in a lot of the videos posted here on NS that kids are able to pull 3's off of practically nothing, sometimes even on flat land.

It also looks like a lot of cats are able to really just flow smoothly with their motions and pop around on nose and tail switching from normal to fakie and back again as easy as if they were just walkin' around.

When I'm out fooling around everything feels awkward and stiff. Nothing "flicks" easily. Popping on flat land from switch to regular and back requires some awkward effort to pull my skis around. It NEVER feels like my skis are an extension of my legs, but rather something I'm having to consciously manage. I think this is in large part to my boots being way to big, but still.

I generally feel like I'm lacking "quickness" in loading and unloading my weight when coiling for spins, there's no "pop". Everything feels too forced.

Now I'll admit that I'm 26 w/ joints that have been beat to hell by 20+ years of skiing and 10+ years of mountain biking, but I'm really trying to push and progress, but it just isn't comin' too quick :)

Any advice or similar experiences?

I already know I shouldn't be gay, or a fag, or a homo, or a pussy, or any number of other things so I've already got that in mind, no need to point it out again ;)
