You can TRY, and you can convince yourself that you are successful, but in my considered view the only way to do this is to become more superficial.
Here is the thing, here is the difference between “everything flows from the center”, and “everything exists in local webs which are interconnected in interesting ways”: if every person on the planet made a conscious effort to love 5 people, no one would go missing.
This is something, I think, most of us can do. To claim otherwise is, as I see it, for most of us, a lie.
Wishing others well in the abstract is certainly possible, and rejoicing in others success is certainly possible.
But I can’t help but think those who want to try and love everyone in truth love no one. They don’t even know what they are lacking.
Better to aim small and succeed than to aim high and fail because you were never serious in the first place.
