Back on MBA track

I have decided to stay in current job for one more year and apply to business schools once again.
I haven't finalised the list of schools yet and, of course, I have no time left for research now :) "Where was my head half a year ago?" - a typical question for many MBA-hopefuls, I'm afraid.

LBS, of course.
And a couple of American top schools (again, no safe choices - challenges, here I come!). I'm quite definite on Harvard and I think about Stanford and MIT, Columbia, Chicago (you'd better stop now, girl, or...)
Last year admission season gave me a lot: friendship, better job, lots of contacts and much wisdom :) I wonder what this one will bring?

And a piece of advice from people who managed to get in while having 60+ hours jobs, sleep and private life is most welcomed :)
