Thanks everyone for all those suggestions and tips.
I will try to utilize many of them as I have not real excuse for not practicing for the next two months.
One thing that I am doing now is printing out a page or two of my favorite music (e.g, JS Bach BC#4) that I know is still quite impossible for me yet to play. Then I gaze at a page of it now and then while I try to do other things such as acquire more rudimentary skills like shifting positions while bowing simple arpeggios or sight reading at a quicker pace than what I normally do.
Towards that end, I purchased a cheap, simple clip-on metronome because I too often tend to forget the beat now and then even for a moderato piece whenever a troublesome accidental comes up in order to break a key signature pattern.
