Some of these "OK/Not OK" judgemental boundaries are for the well-being of others - they are good HUMAN VALUES.
Some are required for the society to have some common behavioural understanding - they are good SOCIAL VALUES.
Some are in place just because some line has to be drawn somewhere for us to react - they are PERSONALITY VALUES (personal likes and dislikes).
Human values - like kindness, generosity, compassion, greater good - are time-tested and can be blindly indulged in.
Social values - like respect to elders, abiding by law, charity, moral rectitude - are for other people's comfort, and should be understood ultimately as a choice of behaviour accepted by us for general peace, not necessarily binding. In our path to "feeling free", this is the segment of our mind most difficult to untangle.
Personality values are some things we should regularly break out of as a matter of practice, so that we do not set into a mould or stereotype. (The breakout should not go against a higher value, though). Some experience may have biased us against people talking loudly, for example. It is important for us to recognise this bias, which is a generalised reaction to a specific incident, and work against it.
After all, values are nothing but mental habits. Like any habit, if they serve a "good" purpose, we should nurture them, otherwise, change them.
When we look at the character of a person as he grows up, we find a definite progression of values.
The child is actually strong in human values, but has not developed the others.
The youth develops personality values, and suspects social values. He decides that human values are a sign of weakness. He is vibrant but no longer sweet.
The middle-aged man develops strong social and personality values. In his pressure for material goals, his human values may sometime take a back seat. He becomes a more rigid goal-oriented person.
As wisdom dawns through experience, the binding of social values diminish again, and human values increase, and old people, sometimes surprisingly, mellow down and become very forgiving. Personality values are sometimes too well-set to break out of, which the old man will laughingly admit.
Let us realise that the whole thing is nothing but a programming and choose to let those programs run which are both self-preserving and beneficial to others in the long run.
