I do not know how others feel, but, there are certain things or sayings that have stayed in my head from childhood - maybe you have some to add to the list.
Anyway, here are a few of mine:
See a penny, pick it up and all the day you will have good luck.
If a job is worth doing, then it is worth doing properly.
One for sorrow, two for joy, three for a letter and four for a boy, five for silver, six for gold, seven for a secret never to be told.
Don't do as I do, do as I say.
Red sky at night, shepherds delight, red sky in the morning, shepherds warning.
Don't count your chickens before they are hatched.
I could go on and on, but these sayings are ingraved into my brain and I wonder if others out there have the same problem.
