haha, i think for regular players, u can practice 3-4 hours a day and its actually more than enough, unless ur trying to improve quickly to play a really difficult song, then maybe about 6-8 hours a day would make the cut.
But how long do u guys practise/play the guitar each day?
as long as it takes, depending on what one wants to accomplish. usually, we practise longer when starting out. 7-8hrs of practice is quite the norm for beginning players.
