Are bad habits formed and generated from the deep subconscious, the upper subconscious, the conscious, or all levels of the mind?

Habits can be, in a sense, generated on all levels of the mind. They tend to be enacted subsequently through the subconscious and/or the deep subconscious, depending on the point of origination and the agenda of the individual and the various levels of the mind reinforcing the need for the habit to exist. So this is a complex subject with many variations and intricacies in the interaction of levels of the mind, let alone the types of habits generated by those discrete levels in particular.
