Also introvert Asian engineer here, quite a bit older, and it sounds like we have different backgrounds. The good part is that you've identified what you don't want. The trickier part is finding solutions. 1. Do stuff alone? - simple as doing suggesting or asking to do things with others. Don't have a roommate? Move and get a roommate. Interview them before moving in. When I was 26, I was tired of being alone also, so I found a roommate. It didn't work perfectly, but it helped me learn how to live with someone else. 2. English - to work on pronunciation, record yourself and listen to it. Practice all the time, listen, and adjust. To work on phrases and vocabulary, don't be afraid to ask people to explain it to you. Tell them you never heard of the phrase growing up. It may spark a conversation and will help with talking to people in general. Like startups, there will be rejection and the fear of rejection. Look at your successes and failures objectively and correct accordingly. Engineer your life =D
