I'm not doing the 35 day challenge, since I already know I'd miss 2 days.  I allow myself 2 days off a month, and that has worked out ok for.. Well, over a year (I haven't really kept track of how long).

But the next month or two, my current hope is to get more used to running a little vid/audio recorder I bought, and to get a good space set up for doing that sort of take.

3 months will be about the end of April, which will be the beginning of my 4th year on the instrument, and I usually take a week or so to do a self-evaluation and re-vamp my practice strategy. 

PS

@Schaick: I recall an interview with the jazz violinist, Regina Carter, where she mentioned breathing.  When she started playing violin with jazz bands, as I recall she got put over with the saxophones.  She mentioned that one of the sax players pointed out to her that just because she didn't *have* to breathe when playing violin didn't mean that she *should* play like she didn't breathe.  She felt that thinking of needing to take breaths while playing violin, as if she were singing or playing a breath-driven instrument, was good for getting her phrasing more natural and for learning to make better use of dynamics.
