21 Days To Make A Habit.

No one is entirely sure where the 21-day rule originates, but it seems to have first been set forth in a book called "Psycho-Cybernetics." It's a self-help book first published in the 1970s, and in it, you find out you can create or break a habit in just 21 days. In 1983, for instance, a woman chronicled her efforts to start flossing and stop criticizing in a piece for "Reader's Digest." The article was called "Three Weeks to a Better Me."

But does it really work for everyone, or are these just the experiences of a couple of individuals?

The reality is, habits are easier to make than they are to break. If you repeat a behavior often enough, those synaptic pathways are going to get worn in. The human brain is a very adaptive piece of machinery. But does that take 21 days? Who knows? Everyone's brain is different, and habit formation also relies on aspects of experience and personality.
