Reddit, what's the manliest advice you've ever received?

Growing up, I've gotten some solid manly advice, but I'm curious to hear yours.

Here's some of mine:

"Don't you ever hit a woman, unless she's acting like a man."

"I don't ever want to hear about you staring a fight, or you'll be in big trouble. But I don't ever want to hear about you not finishing a fight, or you'll be in bigger trouble."

"A limp handshake is for weak men and Communists" (I have Ron Swanson to thank for this)
