Kotowaza of the day: Take a chance

Japanese:

当たって砕けよ

Romanized:

Atatte kudakeyo

Meaning of Japanese:

Strike out and break (it)*

English equivalents:

Nothing ventured, nothing gained
Go for broke

*Multiple meanings for the japanese atatte (from ataru, 当たる) make a literal translation of this kotowaza problematic. But I think the basic idea is very similar to "go for broke." You'll never know unless you try.
