When I first started out I was doing 2 hours of footwork training a day. Mostly just advanced stance stepping from the Leung Ting > Emin Boztepe I spose keith kernschpect should be in the middle in there.. anyways!
I practiced the hell out of coordinating my circle step too. And than I added the "oh **** an opponent is right there right now shadow-boxing element" to it.. and that's what I've been doing since, not enough, but I do it all over the place.. waiting for the bus.. at work when I have a second, though I usually just do IRAS.. definitely all over the house, sometimes in the grocery store.. everyone I know talks about how they are doing wing chun in weird places.
Right now my main focus is building up the strength of my kicks, and being able to keep focused up top while still keeping my feet active. That and a butt load of IRAS stance with poon sau/chi sau.
I want to work on making circle step work for me though.. under pressure, I make a minute crab step instead of shifting my weight off on the one leg, drawing back to the center and than shooting forward to regain original line, I've finally got some guys in class who want to spar, and I am insisting upon working heavily on refining some of our random feed drills to the point where the arms are taking over, and not just, oh he's on the outside of my arm, tan sau before even punching! goofiness. Slowly but surely!
edited out some random words that didn't belong, god knows what else is in here!
