I’m actually quite critical of simplistic notions that often get misused like ‘alpha’, ‘beta’ or ‘sigma’, or the accompanying ‘sigma grindset’.
I just use it because I am on an alpha sub myself and understand it to be a useful shorthand for a whole range of ideas- for me the most important characteristic that I associate with ‘alphaness’ is to completely let go of the need for external validation and to become fully self-determined. A true inner freedom that is reflected in everything one does ‘out there’. That does not seem possible to me unless one has unconditional love for oneself/fully accepts one’s self and past.
