Your capacity to change your attitude and the way you speak is a purely intellectual process. However, until fundamental real-time feedback and profound somatic awareness-oriented change takes place, the core driver for the autonomic response remains unchanged.

Very little comes from things to which we do not commit ourselves. The whole notion of "practice makes permanent" is not a coincidence, but rather, a fairly accurate conclusion of a moral AND scientific investigation on whether lasting change comes from anything other than full commitment.
