Growing up my folks struggled to keep me practicing. I remember the private instructor telling me in front of them that I needed to practice half an hour every day. That sounded like an eternity. Now as a comeback player I try to get in an hour a day, or if I am lucky three half hour segments on weekends. Takes about a half hour to do the daily drills and scales, then a half hour to practice technique (Arban's exercises) or play music I enjoy until I am too tired to play. I frequently find myself wishing I had more time to play. Unfortunately the number of hours I work precludes any more than that especially if I don't want the Mrs to get frustrated with the amount of time I am devoting to practice. Funny how things change.
