I'm not in a startup and I know nothing about LLL but I do know this: if you're firefighting and say that you don't have time to draw breath, and that you don't have time to learn the right way to get things back onto track, then that means STOP! Reassess where you're going because you're heading for a crash. Take some time out to get things in perspective and take the time to do it right. Cut back a bit on those tasks that seemed so essential but perhaps you could afford to skip them for a week or two.
