Do you find it hard to think of things to write about in your newsletter? I used to find that I could think of things I should have written last week. I am still not perfect but I have improved my flow of ideas I have set aside space on my planner each week to suggets topics for myself. As my business is influenced by the seasons I can work out when I should be telling me customers about products they will need for what ever event is coming up.
