You're very right. Learning about anything is a life long commitment and one never truly complete. But it's the wisest ones who know that they don't know everything. Most people don't have the humility to accept or admit to that. You're on the right track.
you are so right about learning being a life times work shall i say :-) so many people on here think they can learn it all quickly . i think one would never learn it all even if they studied for thousands of years. many blessing be upon you, macus
