I've learned how to get people on board with an idea when I have no power to make them. But there's a senior guy who shuts me down in every meeting, and a couple of others who just dig in no matter what I say. I can move the willing, and the ones who matter most still won't budge.
More people experience this than they realize.
You can win people over, but the resistant and senior ones still block you.
If this sounds familiar, the Library can help you find the bigger picture.
