Hindsight advice from older guy to younger guy:
Re: Party - don’t go. You were not invited. I won’t delve into why but if I read into your posts enough it seems you have a few issues with insecurity. This is NOT a criticism, it’s just an observation, and it’s normal.
My real advice is this - go somewhere else, find some open party and join it. Say hello. Ask friendly questions of others. LISTEN TO WHAT THEY SAY.
The greatest secret to being a great conversationalist is DON’T TALK TOO MUCH, LISTEN!
Pretty soon everyone will think you’re the greatest guy to have around. You won’t have to provide any proof of your own excellence, you’ll be the guy who pays attention to others. People eat that up.
If it doesn’t work out, try it again in another setting. Lather, rinse, repeat.
You have nothing to lose but a little of your time. You don’t have to be anything other than a listener. If you listen well and ask pointed follow up questions they you reach the new level of ‘insightful guy.’
The thing is most people give all the answers to anything they are talking about when you talk to them. You just have to be bright enough to listen for them and then point them back to their answers.
I gather by your participation here on this board and admittance that you follow facebook, followed by your admittance that social situations are difficult, you are one of the many younger folk who are more comfortable interfacing with a keyboard than with real humans.
You are going to have to get around this.
Simple rules: say hello, listen more, ask a few questions, speak little of yourself unless asked and then keep it brief, pay attention. It’s actually pretty easy.
This all comes from the former introvert who had to become a tv reporter (long story - won’t describe.)
