Phill Gibson on Banjos and Bluegrass

Knowledge is knowing that a tomato is a fruit.  Wisdom is knowing not to put it in a fruit salad.

So we must also remember:

Knowledge is knowing how to execute a full-fretboard G major scale. Wisdom is knowing not to stick the whole thing in a break.

Knowledge is knowing all the words and chords to all the songs. Wisdom is not trying to prove it.
