Now that's a good advice coming from experience. People should listen more otherwise they will stay dumb as posts, charm in silence however I don't seem find the one to listen to?
It's intimidating as well but what if you don't want to intimidate people you want them to be more friendly.

I rarely got a reply from anyone. Whenever I do get reply it is you must be a playboy or you must have way too many gf and it's not possible to not have a gf for me.
I do joke around but mostly I am a bit serious but things always backfires.

Looking bad is better/how to know if I'm a good guy or bad guy.
I don't think I'm a bad guy, so maybe good guys actually do finish last. While I see bad guys easily getting multiple gf I struggle to find that one.

Any advice to increase my insight perhaps of this world.
Unfortunately, I am inexperience and look down on myself alot tho but it never really made me hopeless.
