Whether it is a 30 day challenge to encourage you to read more, exercise, eat better, or get better at a hobby, 30 day challenges are less intimidating way to develop habits, skills, or just try something new.  Track your finances (to the cent!) for 30 days.  Run or walk outside 1 mile every day for 30 days.  Cut fast food from your diet for 30 days.  Get up 30 minutes earlier every day for 30 days.  The options are endless.
