I don't think it makes sense to say this can't be done. I started my first startup -- and did the majority of the work on it -- while working a 40-60 hours a week job, and spending time (admittedly, not as much as I should have) with my girlfriend. It was insanely hard and stressful, and I slept very little around that time, but it was doable. If you think it's impossible, it is.
