Just smoke some cannabis if you want time to stop (interferes with your ability to filter perceptual information in a linear fashion--nevertheless one's own personal freedom to choose to do such a thing); the rest of us have jobs that require routines. Btw, don't pass the human species off as habitual, we are anything but in respect with the animal kingdom in its entirety (lack of a definite homeostasis in nature). With all that talk about measures, was there a mention of how spontaneity is to be measured? Breaking a habit just to find a new one seems frivolous. It seems to me one would have to be put in a truly unpredictable environment (such as the wilderness) to become less routine.
