You gotta do what's right for you and what you feel comfortable with. Masculinity, alpha, manliness, fatherhood... these aren't things that can be quantified by other men looking to make profit or boost their own ego. We all have to live our lives, we all have individual experiences and situations. The majority of things are true, but you need to create a bespoke version of alpha that aligns with your worldview, religious views, cultural and moral outlook.
There's more than 1 way to skin a cat. I think focusing on being a better person/man and relying on my own intuition has worked best for me. However, not everyone has the ability to rely on themselves and their mind so securely, I get that. I take everything I read, see and hear with a pinch of salt.
