They way you act and behave is based on the way you think. You have to agree with this statement if you want to change how you behave. Technology and computer can be a constraint and limitation on how you socially act because your primary interaction is via chatting online anonymously. This might be a difficult decision to make but limit the time you spend on computers, smart phones, or video games. You have to allocate your time accordingly and spend time interacting with human beings FACE-to-FACE. Go to the grocery store, bank, or a public venue and say a simple "Hi". Take Baby Steps as you progress. Keep getting into the habit of saying hello and asking them questions. Take the courage and confidence. If they don't respond back, don't take it personal and move on. You have to be confident and boost your self esteem up by finding your passion and finding a self-gratification of joy. Engage people despite age and ask them questions. Small Talk can do wonders even thought it might be very awkward for some.
I highly recommend a book by Dale Carneige "How to Win Friends and Influence People" if you have not read it yet. In addition, join groups on meetup.com to meet new people. Take the initiative.
Just get tinder, become a tinder God and bang ever girl within 20 miles of your location then once your body count is in the triple digits the bros will have no choice but to respect you
like i'm not saying i'm opposed to drinking but it's a very much "how daring i feel on the day" thing because you'd have to find something that i actually like to drink
