To 'know Thyself' is considered quite an accomplishment.
The road to the City of Emeralds is paved with yellow brick.
Whenever I feel blue, I start breathing again.
I shall ask for brains instead of a heart; for a fool would not know what to do with a heart if he had one.

If I ever go looking for my heart's desire again, I won't look any further than my own back yard. Because if it isn't there, I never really lost it to begin with!
