Nothing Ventured Nothing Gained.

Have you heard this expression before?

It means that if you don't take any risks you won't get any reward. 

Basically, you need to take a chance if you want to win.

Harry: Should I ask Helen out?

Ed: Nothing ventured nothing gained Harry. Go for it!

Harry: Thanks, I'll ask her out tomorrow.

As you can see, it is a common response to someone asking for your advice  about if they should do something. If you think they should take a chance, simply answer:

Nothing ventured nothing gained

You can tell from the phrasing that this is quite an old saying and it actually goes back to the 14th century!

Weblio says that in Japanese it means:

《諺》 危険を冒さなければ何も得られない, 「虎穴(こけつ)に入らずんば虎子(こじ)を得ず」

Have a great week,
