Reading through a book of Gaelic proverbs* I took a liking to these two -

A' chuiseag a dh'fhàsas anns an otrach 's i as àirde a thogas a ceann.
"The weed that grows on the dunghill lifts its head the highest."
(I know them, I know them.)

Is sona iadsann a chumas o lagh is o léigh.
"Happy are they who have no dealings with lawyers and doctors."

An old favourite of mine is Is cliùtach an onair no 'n t-òr.
"Honour is more commendable than gold."
(The poor man's consolation)
