Great reminder on working on one's habits.
Can you explain more about your tracking system sometime? I think it's the first time you mention it (or I missed the other times). I guess it's an adaptation of Sebastian Marshall's tracking (as is mine).
How are the grades working for you and based on what do you give them (gut feeling, metrics,..)? Personally I mark each day as (WIN/FAIL/OK) and track progress I made that way in a little chart (WIN = +1, FAIL =-1)
