Routines make you become more and more rigid in your thinking. At times, doing the complete opposite of what you want to do may be more beneficial. For example, staying awake when you feel sleepy, sitting in silence when you want to listen to music or walking to your destination instead of driving there. These small acts may allow you to discover fresh feelings and new directions.
