I know what you mean! Today's my second day, and I haven't set a specific length..I will be getting a call tomorrow to set up a date for a job interview, so it will depend on that.. I'm thinking I will stop on Monday, which will mark my sixth day.
Then I think my future goals will extend further and further (my first was 2 days long, assuming i complete 5 days..then I will go for a week, and so and so forth!).
