Well, there’s some timeless advice on these topics, right? The simplest is: be likeable. The reason is that since you can’t accomplish the task on your own, you need people to take your side, and to do that you need them to want you win, whatever the arguments. (“that’s dumb, my argument is better”. Yeah, maybe, but if people don’t like you, that won’t matter)
Another, more focused on societal change is: Move the middle. The middle of the bell curve is where most of everything is, and moving it, even slightly, can have dramatic effects. Also, if you want get anywhere, getting going at all is probably a good move, right? I’m thinking specifically of sorting recycling: it’s mostly bullshit, but the bizdev bros would murder for that kind of ‘engagement’. It’s easier to sell everyone on next step when they’re already on board…
Or, you know, rant about revolution. It’s not going to change anything, but it might make you feel better.
