None is too rich, none too poor, none too young, none too old to enjoy it.

Context

“Cyrus pointed out with pride and pleasure the trees he had planted with his own hand. [I remember a pillar on the Duke of Northumberland’s estate at Alnwick, with an inscription in similar words, if not the same. That, like other country pleasures, never wears out. None is too rich, none too poor, none too young, none too old to enjoy it.] There is a New England story I have heard more to the point, however, than any of Cicero’s. A young farmer was urged to set out some apple-trees.—No, said he, they are too long growing, and I don’t want to plant for other people.” source
