The whole alpha/beta thing could be a decent topic to discuss. I'm only about a 5.5/10 or a tiny bit above on the alpha scale, part of my goal is to become more dominant too. That's been happening naturally as I get more muscular.
Along with my looks improvement, my mind has also transformed a lot. I used to hold a lot of anger, argue with feminists and liberals on Twitter, be part of hateful groups. These are things I've cut out of my life completely. My whole life is a struggle to improve. I can't tell if I'm really good at self-improvement, or really bad, because it's been a few years now and I'm still not at my goal despite making a lot of positive changes. I'm also 100% free from social anxiety (and slowly recovering from general anxiety I think, I get less random panic attacks) which I suffered with badly from about 17 to 19, I overcame this with no meds and no therapy. There have been points in my life where I've been so rock bottom that I considered suicide. This is also gone from my life. I have been free from these poisonous things for 2 years or more now. But as you can see I started at absolute zero.
As for embarassing posts, you would find none. I haven't made any in over 2 years and I deleted those a LONG time ago. I didn't come here for personal attacks so I'm posting anonymous.
