A baby has brains, but it doesn't know much. Experience is the only thing that brings knowledge, and the longer you are on earth the more experience you are sure to get.

To 'know Thyself' is considered quite an accomplishment.

To be individual, my friends, to be different from others, is the only way to become distinguished from the common herd. Let us be glad, therefore, that we differ from one another in form and in disposition. Variety is the spice of life, and we are various enough to enjoy one another's society; so let us be content.

A curious thing about Ugu the Shoemaker was that he didn't suspect in the least that he was wicked. He wanted to be powerful and great, and he hoped to make himself master of all the Land of Oz that he might compel everyone in that fairy country to obey him, His ambition blinded him to the rights of others, and he imagined anyone else would act just as he did if anyone else happened to be as clever as himself.

There is no place like home.

I believe that dreams - day dreams, you know, with your eyes wide open and your brain machinery whizzing - are likely to lead to the betterment of the world.

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.
