Seriously. You have no time for breaks at all. No phone calls. No TV. Maybe time for a hot pocket, but barely. 0 sleep. Lots of high protien food. If you use caffine youll just have a crash and get even less done. Drink tea instead. And unless you have your friends come over and help you pre cut and score everything there is absolutely no way this can be done. And when you get done with a hd model and it doesnt fit you will curse and throw things and that will absolutely suck out all your motivation. Grab some friends, offer some pizza and a movie to watch while you work and you stand a good chance, but solo ? Nope.
