I need a Latin translation

I need the following phrase translated into Latin
“If you are going to do dumb things, you have to be tough.”
It’s for a certificate for a friend that injured themselves dirt bike riding. I’m giving them a certificate honoring their entrance into the Dumb Tough club.

Si acturus es fatua, necesse est tibi durus esse.

(If you are going to do stupid things [literally “stupids”], it is necessary for you to be tough.)

Thanks!
It looks very classy on the certificate. :smiley:
