Where I'm from we have similar sayings:
- Don't dive head first into water.
- Measure nine times, cut once.
And a random saying I just remembered: "Autumn has the eyes of a summer and the teeth of a wolf."
Edit:formatting
Err. What does that last one mean?
- Look before you leap. - Measure twice, cut once. - Stay silent and have people think you're a fool, open your mouth and confirm it.
I'm sure there are many more common idioms pointing towards the idea of "think before you act".
