Practice time 2hrs in the morning if possible,1 hr in the evening.Not every day but as often as possible.
Sight reading a fresh tune .One of my difficulties.Choosing the correct area to play is a bit tricky.Looking a bar or two ahead, choosing the best fingering, looking at the bass to find the notes, also remembering to stick to the Key signature and trying for good technique all at once.Once the metronome is on it all gets grabby and erratic.Once the piece is learned, all is good.
Horizontal playing.Very happy playing across the strings in a limited area.never did much playing up and down the one string until recently.So trying to play as much of the sight reading pieces on one string at the moment, just to try and get comfortable with it.
