I recently attended a half day of training focused on the roles and nuances within the business networking group I belong to. While extremely enlightening and really useful as I work to get a grip on my new role as president in my chapter, I’m struck afresh by the spectrum of differences that we each have as humans.  In the case of the discussions I had, they focused on personality types and learning styles as they pertain to the other members of the group. Extend those classifications to digital marketing, especially as an entrepreneur, and you can begin to feel overwhelmed. It’s one thing to write, say, a message for an email campaign in four different ways to accommodate four personality types, but take the personalization further to learning styles, cultural and generational differences, best channel for communication, etc. and you just might feel that going back to a broadcast “one-size-fits-all” style is just easier, and it used to work OK, so just go for it.  Or maybe walking around wearing a sandwich board!
