## Caption

⏳ The 21-day rule isn't real.

It came from a 1960 self-help book, not a study. Research actually puts habit formation anywhere from 18 to 254 days, with about 66 days as the average for a behavior to feel automatic.

Which means if you're at week three and it still takes effort, you're not behind. You're right on schedule.
