It's a proverb which means --> "Inquisitiveness can lead one into dangerous situations"
Joke for today:
Mother - "Don't ask so many questions, child. Curiosity killed the cat."
son - "What did the cat want to know, Mom?"
Everyone have level of curiosity of their own. "what if I do that.." ; "what if Not"; "what if I go", "what if I don't"... but sometimes, long thinking will not get things going.
Personally, I think, It's ok to be curios but we have to confront it with knowledge...
