Athiest and immoralist here. Even I have certain codes I live by. I don't do it out of fear to some god, it's more of a sense of pride with some and just who I am with others. Now I don't know what you define winning as, but to me winning is making good money, getting good pussy, and living a good life. Does my behavior that stems from my personal ethics help any of that? In some ways yes and some ways no. But sometimes it's the small things that matter more than notch count or bank statements.
Here are some of my examples:
Work before pleasure. I like to do everything I don't want to do first. I feel it clouds my mind and I can't really enjoy stuff if I'm thinking about shit I don't want to do. And I can't help it so I get work done first. I've been that way since college, and I feel like I have really benefited. Not just work wise, but it makes the pleasure more pleasurable when you have literally zero stress.
Bros before hos. My friends all trust me around their gfs because they know I never have or ever will be so desperate as to steal their bitches, no matter how fine. They know I live bros before hos, and they for the most part are the same way with me. I'm still invited to their parties and activities while the ones who put women first aren't any more. To me it's simple: Don't risk a friendship and a social circle that can lead to many women for just 1.
Mind your money. I refuse to spend money on girls who aren't my girlfriend. This is good in 3 ways. 1: I save money. 2: They know they can't trash talk me in any way that would harm my SMV after were through, and if they do, no one would believe it. After all, who would believe a girl who's complaining about bad sex after she has spent so much time having sex with me without getting anything else out of it besides maybe some companionship? It just wouldn't make sense. 3: Identifies girls just looking for beta bux. Yeah they are still fuckable, but I'd rather not have to jump through the hoops and spend the money that is usually required for these girls.
Be respectful when it's due and of reputable character. I'm not really into monogamy or LTRs, but in regards to the few of them I've been in, I've never cheated. Mostly because the girls I were with were almost snowflake like with awesome personalities, bodies, faces and hobbies... but even if things went downhill I'd just dump them and look for someone else or take a little break from girls rather than cheat. Because of this my exs have mostly good things to say about me, and I'm still good friends with most of them. This increases my exposure to other girls, girls who have heard all these good stories from my exs. Ain't no seed planting like ex seeds. It is social proof in its most powerful form. Now if only they had some hotter friends...
So yeah, I probably gave up some pussy, but my money situation and social situation is in a much better place for it. I know guys who are kind of like the opposite of me. Guys who make passes at anyone and will fuck anything, anytime, anywhere, spend money to make it happen if they need, and they always seem to be in fucked up situations. They burned bridges between them and their best friends, spent money that could've improved their lives on drinks in exchange for 2 minute conversations with girls, ruined decent relationships for fat girl sex, some even alienated pretty much everyone around from them. Are their notch counts higher than mine? Most likely. But they really have no true friends left and are verbally bashed by almost everyone they've ever associated with. They can always move on, but I like my friends, my home, my entire way of life really. The way I see it is there's no need to have to pick up and grow new roots just for some pussy.
