It’s chicken feed.
When small people cast big shadows, it means the sun is about to set.
An ant may well destroy a whole dam.
Little and often make much.
Don’t use a lot where a little will do.
Slow as a snail.
Slow as molasses in January.
A snail’s pace.
We are not so much concerned if you are slow as when you come to a halt.
If you snooze you loose.
