I don't mean doing it one time on one aspect of your life, I mean to say that we have a habitual way of living that is so automated that it's something we don't even think to question. Even if we do question it, making a permanent change is much harder than we anticipate. You may brush your teeth first on day 1 and day 2, but there is a pretty good chance that by day 3 you will be in the shower then remember you were supposed to clean your teeth first, because your habits are extremely hard to break.

Deciding to make a change is not freedom, freedom is realisation of change. A slave can decide s/he wants to be free of their masters control, but unless s/he can make it so, s/he is not.
