I call this taking yourself on a date one time a week for four weeks. I did this and had so much fun. It really helped me to learn to love my own creative self.
To get your imagination in motion you need to expose yourself to different ideas, people, and places. It's time to leave the nest. If you want a dynamic imagination, you need to infuse it with dynamic ideas. Take your brain out for a walk. Get out of the house and experience something new. A dance show, a lecture at the local university, a band that you would never normally see, a conference outside of your discipline- anything outside of your ordinary that might create a spark. Start to open yourself to ideas that live beyond your comfort zone. Be dogmatic. For each of the next four weeks choose something different that takes your mind somewhere it would not normally wander. Think; open, experimental, experiential.
