If you don’t have a plan you plan to fail.
When you are establishing a marketing plan, you can have a plan that is up-to-date or you can have a plan that is guaranteed to fail. That may sound a little harsh, but stop and think about how much things change in the span of a few months or even a few weeks. You should periodically go through your marketing plan and make sure that you tweak your strategy. This will help you be sure that your marketing strategy will survive the next stages of your business.
