Your Habit Streak
Habit streaks measure how many consecutive days you have maintained a habit.
Streak (days) = Today's Date − Start Date
Research on habit formation:
- It takes an average of 66 days to form a new habit (Lally et al., 2010)
- Some habits form in as few as 18 days, others take 254+ days
- The key factor is consistency, not perfection
Motivational milestones:
| Days | Milestone |
|---|---|
| 7 | One week — you’ve started! |
| 21 | Three weeks — building momentum |
| 30 | One month — real commitment |
| 66 | The “habit line” — it’s becoming automatic |
| 100 | Triple digits — impressive dedication |
| 180 | Six months — lifestyle change |
| 365 | One full year — it’s who you are now |
Tips for maintaining streaks:
- Start small (2-minute rule)
- Stack habits onto existing routines
- Track your progress visually
- Plan for obstacles in advance
