Because your goal is to get to thousands of hours of practice. I think the probability of burnout is way too high if you put 6-8 hours of practice in a day. The only way to get to thousands of hours is to practice every day for a long period of time. With 6-8 hours it's very easy to say to your self "Well I did put in all the time yesterday, so today I'll take a break", and this in turn tends to lead to finding yourself spending weeks/months without practice. Slow and steady and whatnot ;)
