One thing that is rarely touched on in TRP is humor. That makes sense, because time is better spent on things that have direct and promising return-on-investment, which is why this subreddit advocates lifting, studying/working discipline, and understanding social dynamics so much.

But I find that time and time again, the limiting factor to my interaction is simply humor. Or rather, giving off a good, light-hearted, fun vibe. It's very easy, and only natural, for people on their obsessed with success/self-improvement to take themselves too seriously. This is a trap I have fallen into a few times but have gotten much better through meditation (letting go, and just enjoying the process).

So to be more specific, what is your sense of humor and where did you acquire it? What are good ways to learn humor (in the context of charm/game)? No one should aim to be the class clown, obviously. That said, having a few pointers in developing a "versatile" sense of humor would enable one to much easily engage in social interactions (Law 48: Assume formlessness); which would have the subsequent benefit of making you more likeable, and making people more malleable to your influence.
