What habits in your life are in need of a change?

Anyone who has ever flown on a plane somewhere has witnessed the well-memorized script of the pre-flight safety presentation. With the attention of about 5% of the plane, they go over how to buckle and tighten your seatbelt, where the emergency exits are, how your seat cushion floats, etc. There was always one part of the presentation that has stayed in my mind, through childhood and even today.
