> The real secret is to save your energy for the people who are most likely to be interesting to you. I think this is the real gem. There are people who do well socially and are energized by other people. That's not me. I can do well socially, but I have a social battery - people drain me and I need to regularly be recharge by being inside my own head for a while.
It's not that anything drains me, I just can't get myself to pretend to care about strangers.
I don't imply you have to care about strangers, but there are tangible benefits to maintaining a balanced approach (and that, for introverts like us can mean doing more than we would if we just follow our guts).
After all even if you don't care about strangers, being on good terms with them, or even making the occasional friend will have a positive impact on literally everything else that you actually care for, be it your own well being, your projects, etc.
