Well said. For my part: seek beauty and happiness. Don't make others sad.
The last part is far more difficult. Why? As someone said, "We have caveman emotions, live under medieval systems and have access to god-like technology."
Perhaps a simpler example: when driving on the highway, stay out of other driver's way, enjoy the experience and don't cause danger. I can't control how others drive, but I can get out of the way.
Yes, when life puts you in a position where you're insulated from the consequences of your actions, just enjoy it :)
If your role is actively making life worse for thousands of others, that's their problem.
When you've been offered the privilege of an uncomplicated life in a complicated world, just grab it by the neck and take it, discard the complications as something for others to deal with!
When you take into account how much corporations cloud the effects of your work from you, and how easy (normal, in fact) it is to live in a bubble where you don't realize the level of suffering of others, then when you say
> no matter who you are and what your role is
that view is exactly what you are endorsing. You may not feel that way, but unfortunately, you don't have to explicitly feel it in those words to act exactly in accordance to that.
Going about your life without concern for how your actions affect those around you is what some might call selfish :)
You feel that's the best give you can give yourself. Others might feel the best gift they can give themselves, is a community.
Perhaps a war criminal might find equal personal fulfillment in seeing a wildflower as a doctor. But there's more than one ingredient in a happy life :)
How complicated.
The best gift you can give yourself is enjoying the simple moments of life, no matter who you are and what your role is.
And that's all this is about.
