my private teacher tells me every lesson that the most important thing for a player at my level (high school) is a good daily routine. he also says that how long you practice is not nearly as important as how critical you are of yourself when you practice. so my question is for some of the pros: how long is your routine and what specifically does it consist of? how long should it take? is it better to have a shorter routine you do more often or a longer one you do less often? should it differ from one for my level?
thanks in advance!
