So, how's the vicious circle (caffeine, wine, cake, lack of exercise, lack of fresh air, fingerpicking?). Good on the first, rubbish on the rest. The erosion has begun, subtly, out of habit.
Where has my virtuous circle gone? (exercise, getting up early, proper relaxation times, low-gi food, drawing, keeping in touch with the people I love)? These all actually support the creative process.
A day off to focus on getting back on track. Maybe even back on the track, if I find the right music to run to.
