Recently I heard "visionary" defined as a direct, decisive, dominance-oriented leader. Like: "Of course he can't see the big picture! He's a visionary!"

I realised that I disagree with that definition with my whole self. If someone can't see -- indeed isn't even trying to see -- the big picture, they're not a visionary to me.

To me, a visionary is someone with a 360-degree view: opportunities, benefits, costs, challenges, unintended consequences...who still fosters a specific call to action.
