Education is a wonderful thing, provided you always remember that nothing worth knowing can ever be taught. -- Oscar Wilde
Aah, yes. Experience is the key. Ain't that the truth? Or, if I can get religious on you for a moment, here's one from Proverbs:
Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding. (Prov. 4:7)
Even with experience, not everybody quite gets it. Some folks go through life experiencing a lot of different things, but never take the time to think about what they've seen or done.
So, there you have it: Education, Experience, & Understanding. It takes a little bit of each to figure out what's going on in this world.
