In order to meet new people, you have to get out and make yourself available to new acquaintances. It’s highly unlikely that you will meet many people while sitting alone in your living room watching television or playing video games.
It’s one thing to want to meet new people… but it is quite another thing to actually start meeting new people. If you really desire to start meeting some new people try making an effort to go out at least 4 nights a week and engage in an activity that you enjoy.
