Simon Sinek,
@simonsinek, says being a bad friend does real, measurable damage, not just to feelings, but to how people think and cope.
When we are bad friends, we leave people feeling unseen, unheard, misunderstood, alone.
That's bad for anyone's mental health, anyone's ability to cope with stress, anyone's ability to think through problems and seize opportunities.
He's not where he is despite his friends putting up with his selfishness and self-involvement, he's there because of it.
Good friendship isn't just comfort. It's infrastructure.
