I'm a regular reader of your blogs and also have read some of your books (and must say, I haven't read such good SF in a long time). I'm a 19 year old and I just got in college, where I'm studying eletrical engineering and have a sort-of relationship with one girl in another country, I go to the gym, and reading not only your books and blog, but others in this corner of the internet I realized how wrong was my belief in the nonexistence of God, so I'm making my way back to christianity. I was some time ago what I would describe as a lower beta, but since the I made some improvements.Gym is good. Reading is good. But what is missing from your description is interaction with others and service to them. I sense a little fear in your description of your mediocre conversations; why are you agreeing with really stupid things? Since you are a Christian, remember that you are not given a spirit of fear, but a spirit of boldness. You cannot become a better man by compromising with lies and foolishness out of fear.
I'm still kind of shy, being really an introvert, and altought I know I should overcome it by talking more, I just can't have a good conversation with any of the people my age, as almost all of them are just brainwashed liberals, so all conversations end with them saying something really stupid, me agreeing and then politely excusing myself and going somewhere else. Not only that I don't have the drive to go to places, visit other countries (maybe because I've already done that in my childhood), but, at the same time, I don't think only sitting at home reading books and going to gym is going to make me a better man.
So, what I want to ask you is this: what should a 19 year old like me do to become a better man, a better christian, and and to help restoring western civilization and it's people?
So, that's the first step I would prescribe for you. The next time someone says something really stupid, don't agree with them, but politely explain to them why they are incorrect. Don't be disagreeable; sometimes it is okay to simply smile and hold your tongue. But do not ever falsely agree with something.
I'd also look for an opportunity to volunteer somewhere. As an introvert, you need a reason to get you out of the house, so find one that will allow you to help others in some manner.
The ancient Greeks believed in strength in body, mind, and soul. With the gym and with your books, you're already addressing the first two. But now you need to address the latter too. And always pray to God for guidance. He will provide it, even if it is to places you had never imagined going.
