Have you ever heard about "Morning Pages"?
In 2011 I studied "The Artist's Way" at the BBAC in Michigan. One of the major tools to trigger creativity recommended are "Morning Pages". 3 pages of writing (long hand) first thing in the morning. With tons of things to accomplish I had no idea how to bake it into my schedule - but I made it! So far I have written hundreds of "Morning Pages", not missed a single day. It helps me with new ideas, creative thoughts, solutions and ... getting clearity on priorities and how to proceed.
