When you are changing a habit, you substitute a new habit for the old one. To jump start this process, make the new habit fun. It will probably need to be a lot more fun for it to even begin to be enticing.
People like surprises (as long as the surprise is pleasant or fun). Research on the brain shows that surprises capture human interest and attention. There is also research to show that things that are unpredictable elicit activity in the parts of the brain that anticipate rewards.
