happiness is a chemical reaction.
and i think it can be created when one dwells on the idea of being free.
but i think the same mechanism that causes one to dwell on the idea of being free, can be manipulated to cause one to feel otherwise.

therefore it would be good risk management
to be part of multiple models that potentially causes one to feel freedom.

that would mean that it could be advisable to form multiple sub-identities, each with its own history that explains its existence.

one example could be:
1) identity at work
2) identity when alone (eg religious/political affiliation, social cause)
3) identity at social settings (eg, family, friends, strangers, neighbors, overseas)

i do not believe there is any system that merits our total trust that it is complete good-willed in making us free - all systems need a self-preservation mechanism that works for itself. each system tries to be complete within itself, so that it denies the existence of other systems. yes, they try to be in harmony, but is that really the case? and let us not forget the human ability to "empathize", forming pre-conceived ideas that are derived from a vicarious experience, potentially creating among participants a reality that didn't initially exist.

wait, there is one other system that is less prone to such weakness.

it is one's basic perception.
to be in the present, hearing the sounds, smelling the scents, feeling the physical heat or pain or pleasure - and resisting trying to interpret any of them. this leads one to a model of explanation of reality that "it just is" - and experiencing the freedom would be dwelling in this state of "just is"-ness. Because this is based on your own perception, you can tweak it to your own advantage.

but the difficult part is resisting the temptation of interpretation.
human beings as a species have chose cognition and reason as its means of coping with change. this choice i think, is an effect of the mechanisms that works out for the self-preservation of the life of the human species - which of course, never promised to be kind to the individual.
