Nine hours per day? Maybe....maybe not. That much practice might actually be detrimental... but not always. You get out what you put in is the GCSE (or high school) way of looking at it. There's actually a lot more going on.
Take the following analogy: Two people living in Ireland want to get to Russia pre flights or common knowledge of the globe etc. The first guy declares his dedication to the cause and says he will spend every waking hour to the cause and sets off right away. He doesn't know everything about the route but he knows the direction and he's got a compass so everything will be fine...
The second guy, sits back and considers his options. He then spends a month talking to all the people in the know about navigation and what exactly is between Ireland and Russia and then takes the time to make sure he has the right boat, the right stuff for getting across land and adequate supplies. He then took a month off to make sure he was absolutely prepared mentally for the journey.
Prizes for guessing who got there first and with there well being still in tact...
Obviously this is guitar playing, not travelling but hopefully it'll get you thinking in a certain way. I'm going to be posting a full article on time management up at www.alloutguitar.com
soon.... you can find the first part of that series at

which leads up to the topic we're discussing here. Discussions are welcome.
