You've asked a lot of questions regarding a lot of topics but I'll break it down as best as I can for you:

"how to build a good social image?" - You need to fully express yourself and "be you", people are always attracted to people in the group who are not afraid to express themselves fully and truly not care, people look up to them and seek their permission, because a person who fully expresses himself sort of "sheds light" on the environment!

"How can i keep it interesting?" - Very simple, if it's interesting to you it's interesting to them, as long as you feel good in your body and you fully express yourself, people will want to hear

"How to make girls attracted to me?" - With most people you talk to, I want you to fully express yourself without holding back, and when you see a girl you like you also express that. If you are playful with most people, with her you'll be a bit more sexual.

How can I out beat another guy? - Don't focus on that, if there's another guy in the group and you try to "out beat" him, he automatically wins because it shows neediness from you and a lack of confidence (the need to impress people), just be yourself and say whatever you want to say (again, fully express yourself), if you truly feel good and don't care you automatically outshine him and people would notice you!
