Even if you're shown everything, it doesn't mean you know everything, understand everything etc. For example, you can be shown a technique, practice it etc, but until it clicks with you, it's not really going to be a useful technique for you because you don't understand it.While reading thru some of the various posts on here, I've noticed some who seem to wonder why our teachers don't show everything to us, why they leave some things 'hidden' rather than just come right out and give us all of the 'secrets.'
Now, IMHO, I'd rather have my teacher make me think for myself, rather than just saying, "Here ya go Mike! I'm showing it all to you so you don't have to do any legwork. I've done it all for you!"
You have to make that journey on your own either way IMO.
