Be kind Be confident ( eye contact, speak your mind - be honest, don't say anything to please anyone especially her, she will constantly test you and you must win) Lift weights - Increases testosterone and added benefit of muscle growth if combined with a good diet and sleep. Don't do excessive cardio. Help others without expecting anything in return. Do it for your wife every now and then. Surprise her, give her a full body massage, do the groceries, don't expect anything from her. Be faithful. It's the main virtue of a man, faithful to yourself, your goals, God, your wife etc. Be responsible for all the actions that you take. Never complain - Act like a hard man even when you're not. Overtime, you'll be tough as nails. Stop being silly, overly playful or romantic. You can be romantic but not more than her. Read 6 books a year at least. 12 books is even better. Balance between your primal and social chemistry. Some "women" label men as dogs, dogs are nothing but a tamed beta version of wolves. Wolves are tough, loyal, dominant. Men in the past were very primal and were like wolves. Urbanization has ruined the primal setting of both men and women. Don't go overboard but be 75% wolf and 25% dog. If you're more of the dog, she won't respect you, If you're full of wolf, she will simply cheat on a wimp with you, your genes are more likely to survive in the caveman period.
