Sometimes it's good to work in a method you normal wouldn't consider the best for the project at hand. Breaking free of your creative routine is an important tool, not only in refreshing your artwork, but also in making new discoveries. If you just stick with what you know, then you will grow extremely familiar with that, but never actually grow as a whole.

Personally, I often find it difficult to disregard the "proper" methods of drawing and working, fused inside of me from schooling and experience. For example, no matter how much I try to draw like a child, it is never anything as unique, innocent and unrestrained as a real five year old would actually produce.
To break free, I like to just grab a random medium, and start to create, without any burden or expectation of producing something great. Shown here is a recent sketchbook doodle looking out the studio window, done in large pink oil pastel. The pastel specifically forced me to ignore details and realism and just draw away. It's certainly no masterpiece, but rewarding all the same.
