Fair enough - I wonder therefore if it is potentially a question not of how one prepares for applications but how one studies? I had friends whilst I was still at university who had similar issues, but found instead that it came as a result of studying inefficiently. I can't pretend to know what your degree is or uni is, but surely they must not have an expectation that one needs to work any more than max 9-7 ish Mon-Fri.uhm if I tell you that typically I spend most of my day, everyday (including most of the weekend), on my academics would you believe me.... haha... just because the deadlines and reading never stop. I've been taking shortcuts and disregarding some things (for example lectures and some pieces of reading) just to make some time for apps but it is having a slight effect on my academics lol - which means I need to lock in so deep after apps are over to make up for it all...
Then again, there's no one-size-fits-all, but based on how successful you seem to have been so far in your applications, you must be doing many things right!
