It's definitely easier to give advice. Less easy to listen to someone giving advice. Easier to see bias in another person, less easy to see it in yourself. Maybe that's why it's edifying to read stories, to watch films and observe other folks living their lives. You can put yourself in someone else's shoes, try on someone else's hopes and worries, float outside of your own narrow corner of the Universe, and try to imagine what it's like to be someone else. Maybe you can learn who you really are by imagining being someone else? Is that how we develop empathy? And compassion? For others? Maybe.
How we choose to live, who we choose to live with, what we tolerate, what we don't tolerate. What we imagine. Where we put our intention. Who we decide to love, who we shun. This is all just long-form improvisation. How do human relationships work? Why do some relationships flourish over time, over a life, and some don't? Why do some relationships work, and some decidedly don't? Beats me.
We all have to live with people. Not an easy thing to do. We have to live with ourselves. Not an easy thing to do either.
