A motto when internalised can be very powerful. It becomes something you do;Something you are.
Some of my favourite are: Sapere aude and Acta non verba.
An excerpt from a blog https://leveragethoughts.substack.com/p/mottos-ideals-and-su...
" In 1662, The Royal Society, which was formed in 1660, was given a royal charter by Charles II. Its motto is Nillius in Verba which means take nobody’s word for it in English. This motto was intentionally chosen; At this time in the west, the objective of most educational institutions objectives was to pass on knowledge from ancient Greece. But here we had the Royal Society, at that time, choose a motto which means that evidence is the cornerstone of its existence. Evidence requires repeatable experiments in science. This was not the norm in the mid 17th century."
