Agreed, but don't things change all the time? :)

This is what makes valuable the understanding and knowledge of the things
that remain common and unchanged, the rules and laws in every science and
discipline.

If one doesn't strive to explore and acquire these and doesn't have the
feeling of constantly getting deeper, then this sounds like a lost
opportunity to grow...

Isn't this the base for our evergoing education and development, and
probably the most permanent and unchanging goal?

Just saying, and not in the mood to argue :)

Have a nice weekend!

Thanks,
Dimitre
