“The vast majority of unteachable people can learn anything when properly motivated to relate.”
Take caregiving for example. Nobody can force anyone to give care but if someone you love needs to receive improved care you become more willing to respond and learn to give whatever it takes.
The crux of this situation is that learning to give better care is time dependent and caregiving becomes woefully inadequate if it is not learned and practiced regularly.
Most will accept the fact we can not know everything. The difference is some if not all must begin learning now to become caregivers if there is to be hope for the future.
