To laugh often and much ... this is to have succeeded. Probably not from Emerson: here's the full quotation and the story.

Some will always be above others.

There is always a best way of doing everything, if it be to boil an egg. Manners are the happy ways of doing things.

If thou fill thy brain with Boston and New York, with fashion and covetousness, and wilt stimulate thy jaded senses with wine and French coffee, thou shalt find no radiance of wisdom in the lonely waste of the pinewoods.

Sleep lingers all our lifetime about our eyes, as night hovers all day in the boughs of the fir-tree.

A man is what he thinks about all day long.

A party is perpetually corrupted by personality.
