Encouraging life long learning is about developing a thirst for knowledge, there is no end to what one can learn, the possibilities are endless. As the Buddha said
"there are only two mistakes one can make on the road to truth, not starting and not going all the way"
The benefits are not obvious because we are socialised to believe that the end point of school is a vocation, a job, a career. But an education is not an end in itself, education is a way to discover our true selves, to realise our full potential. That journey never ends.
