This is the way things need to be though. You're not Elon Musk's rich uncle. If changing the fate of the entire world is your goal, you will die unaccomplished, frustrated and be miserable the entire time. It's beyond your control, even collectively, and obsessing about ambitions beyond your capabilities only leads to madness.
Tend your own lot in life. Fix the things you can. "Climate is heating up" should not mean "design, launch and deploy a functional solar shield;" to you, it should mean "migrate somewhere cooler." Once you're capable of achieving small goals like saving your own ass, then you can afford to be more ambitious and worry about everyone else's.
Sure, but that's not what I was advocating at all. I was very particular with my words in suggesting tending your own lot first, then helping others instead of the other way around. (People that only look out for themselves generally don't need to be told to do so!)
It's the plane-oxygen-mask situation. You can't fix global warming for everyone without securing money and influence for yourself. So focus on securing those first. Empathy unchecked by logic is just hysteria.
