With thanks to John Innes for these modern proverbs:
It is in the cavities that the larger crystals grow.
(A Geologist’s proverb for the moments of quiet or silence when inspired thoughts or explanations come to mind).
The telescope of humility
sees further than the lens of pride.
Economy of effort
is not the same as laziness.
There are old pilots and bold pilots
but there are no old and bold pilots!
It is better to give than to lend
and it costs about the same.
