What can be learned?

I haven't found any useful posts on this sub, so why not make this post useful? A lot of people say "You need to improve your social skills", but rarely mention what they mean by that. If you feel like it, write down some advice for the people on this sub.

I'll start: You don't need to reply to every question and give out all your personality in one go, like it's all meaningless. Deflection is an overlooked skill and so is taking calculated risks. Allow yourself to lie a little bit every now and then.
