Why would someone even have it as a goal to know all the people like ourselves?
Seems impossible, impractical and perhaps even undesirable or upsetting, as there’s only so much time and attention I have for the people I know. Well, actually currently I could use some more good friends, but after a certain point the problem becomes finding the circumstances for those I know.
Oh, and also the choice of who we do make friends with and how we spend our time with them, how open they are to what kinds of people and activities (and sometimes issues such as whether they want you all to themselves or not).
As for finding people, I’ve found that the courses I’ve taken on communication and empathy have helped how open and available I am to people, making meeting and forming friendships much more likely. Also the choice of place and how we spend our time.
