no matter who you are
Relationships are tricky. It's impossible to keep track of everything, to make sure that you're not wasting energy on the wrong people, or that you're not letting valuable friends slip through your fingers.
It's a problem of scale. With potentially hundreds of different acquaintances, how do you balance between them all? How do choose your closest friends, your mentors and teachers, the people you care about, and the people you ignore?
Despite what you may have been told, being overwhelmed doesn't mean you're bad at dealing with people. It just means you're wildly... inefficient.
