—“Work on yourself, King”. The only thing worse than “Christian self-help” is secular self-help. The so-called “manosphere” and the alpha-dog talk tells you to make yourself better, because in that improvement you will find meaning. Experience reveals this to be false. Even now, as you write, and you read, you cannot explain where the joy comes from, if it comes at all. To what end, or for who, are you making yourself better? For people? Why? Does anyone notice? Or care? If so, that is not why you’re doing anything. If not, what’s it matters??[1][2]
Then who are you improving yourself for? For Christ? He is making you better.
Perhaps it is best to take a passive view of “improvement”. You have found a circle that is trying to guide you, assuming you let them in, and follow a God whose primary objective is to make you more like Christ. You are your own worst enemy when you are the only one in your head.
