Good topic brother. Being a man to me...
Keep your word. If you say you are going to do something, do it.
Be there for your family. Me personally, I have foregone things I want so I could buy/loan/give money to my family. Do what you need to do for family no matter what IMO even if it hurts you personally, and never let them know it hurt you IMO.
Admit when your wrong. I know many guys that will never admit they are wrong. My opinion, if I am wrong, I will admit it. A man will always admit when he is wrong.
Help people, don't be smug or holier than thou.
Lastly...just try to help people. Trust me I am NOT a people person lol. Every test I take tells me I am an "introvert" and I honestly do not like people. All my hobbies prove that (Bonsai, fish keeping, fly tying, rod building) all solitarie hobbies,yet, if someone needs help/advice, no matter what I will be there to help them, just ask guys here.
I could add more but I think that covers most IMO.
Oh...and a beard!
