Get in the habit of creating a plan for every marketing activity you decide to implement even if you already have an overall marketing plan in place. Writing it down forces you to research and gather information, which helps you make better informed decisions as opposed to assumptions.  This plan helps you measure the success of the implementation. Planning your marketing helps you drill down on the details that you may have missed out on without some planning. Not only that, it helps with delegating tasks as well if you become overwhelmed.

Planning is what distinguishes a successful marketer from an unsuccessful marketer.
