We generally hear people talk about habits in a negative context — like smoking or nail-biting. But habits can also be positive and constructive! A habit is simply a behavior that's repeated so regularly that it becomes almost involuntary–and once a habit is formed, it's very hard to break. That's why it's so important for marketers to develop great habits.
Under the Covey philosophy, the first three habits are all about improving from the inside out. These habits lay the foundation for your actions, and they typically aren't visible to the outside world. To me, this equates to the planning and data management that creates the foundation of a solid marketing strategy. Habits 4-6 in the Covey philosophy are about the things you actually do. Similarly, once you've got your plan and your data in place, you can confidently start executing your various marketing campaigns. Finally, the seventh habit is all about continuous improvement and renewal–I think that one is pretty self-explanatory!
