was it worth it?

We rarely stop and ask ourselves. It is hard to stop and ask, not only because the money dries up, the cv dries up, the prestige* plummets; but more because if the answer - heaven forbid - turns out to be a NO, then what on earth have we been doing so far? And what on earth could we do next?
So - how about 'so-called human rights education': what would it mean to answer 'yes' (or no)?
- that the work has had some positive effects (made people happy?)
- that the work has had no negative effects (done no harm)
- that the work has had more positive effects than negative ones
- that the work was very well-intentioned (and the effects cannot really be predicted)
- that the work will... very likely ... lead to unimaginably positive effects (when?)
- that we (probably) could not have done anything more worthwhile in the given time and with the given resources
- that we could not have made a greater contribution to human rights (at this moment, given the resources)
HRE is expensive. And it is not as though there are not a million other far more urgent things we could be doing NOW for human rights with our energies and the available resources. Can we justify armies of well-intentioned educators taking the slow (and expensive) road?
And could we ever answer 'no' to that question?
* I wasn't aware before that the original meaning of 'prestige' was: an illusion, a conjuring trick, a deception an imposture. Funny that we happen to have mislaid that derivation.
