There is an envelope to habit.  Anything I repeat - any thought, interaction, action - will require cognitive effort and have an unpleasant character at first, will after this (if I push through the discomfort) begin to cause enjoyment and take on a life of its own, and eventually become automatic and exit my awareness at a third and final state (think of learning to drive).   There is nothing uniquely human about this - it is simply cybernetics at work.   It may very well be a universal law governing all of creation.  I can remember that every action I take is shifting something about my overall character.   Obeying the strange hydraulic cognitive laws that circulate my passions and attitudes - and choosing to cultivate them - this is affirmation of the will to power at the most basic level
