Movement and change, that is what is constant, nothing settles, nothing stops and nothing stays perfectly the same. We have to train ourselves to adapt to change and movement if we want to be ready for life.
It is curious that so much of education is NOT that, so much of it supposes that one reaches some plateau and just relaxes. That you should work your way to some goal and then it is happily ever after in a still, repetitive same-ness.
