practice thrift at home but be amply provided while traveling

fitting in and out, like dog's teeth

The pot is empty and the stove is cold.

chatter away

In one's seventies and eighties

have extraordinary poise(with unusual deportment)

Abandon private interests

Keep in mind

a thousand or slightly less

Beat the ice

rack one's brains for ingenious devices

be more beastly than beasts

by various subterfuges

diligent and courageous

overhaul thoroughly(reform radically)

Stand firm and unyielding

a great cause for a thousand years(an eternal lasting enterprise)

Love is not worth it.

broad day(the light of day)

At sixes and sevens
