Running a marathon, writing a book, or learning piano. These are big undertakings that require discipline and practice. The harder we work each day, the faster we'll succeed, right?

Wrong, say authors and podcasters Jami and Jeffery Downs. Biting off more than our daily chew can lead to a cycle of discouragement. Instead, commit to laughably small steps: Write one sentence a day. Practice for five minutes. These micro goals are much easier to sustain, and when you keep the streak going, you'll find that sentences turn into pages, and minutes turn into skills.

A revelation in their personal lives lead this husband and wife team to develop "Streaking," a philosophy of personal accountability that applies to anything: Learning, personal relationships, and health.

Jami and Jeffery speak with Whitney about the myths of habit forming, and why some tasks — no matter how often you repeat them — will never become automatic.
