E. Cobham Brewer 1810–1897. Dictionary of Phrase and Fable. 1898.
Keep your Breath to Cool your Porridge.
Look after your own affairs, and do not put your spoke in another person’s wheel. Husband your strength to keep your own state safe and well, and do not waste it on matters in which you have really no concern. Don’t scold or rail at me, but look at home.
