That is very true, but I use GTD to handle all of the stuff that are not important to the big project I'm working on. Groceries, household chores, personal finance, emails to random people, phone calls, car maitenance. Most of the things on my list I can't do right now anyway, but don't want to forget later. The end result is that when you are working on the big project that matters, you aren't distracted by constantly thinking "oh crap, I have to remember to pickup bread tonight, and call the DMV and find out why they lost my title, and setup a dentist appointment" (all things on my todo for today), but you can sit there and focus with nothing random coming up in your head.
