To ‘school’ means to habituate to something, so of course to ‘unschool’ means to unhabituate from certain beliefs or behaviors.
The longer you have been ‘schooled’ to certain practices that are no longer effective, the more ‘unschooling’ may be required to change your behavior.
So it just makes sense that children need less unschooling than their parents and other adults.
We have time to prepare our children for the future, but we adults have to change our shoes on the run.
What habits and beliefs, if you could change them would make the biggest impact on your total life experience?
