A Little to the Left

As the achievement states, in order to earn this achievement, you must complete 14 consecutive daily tidies in a row. If you miss a day, your progress will reset. You can check your progress on the steam achievement page as it does display your max consecutive days in a row.

Personal tip, if you are unsure if you've done the daily tidy for the day, open the game and check the star before midnight local time. The next daily tidy will generate at midnight each day. Otherwise, set an alarm or find a routine that will work for you.
