When trying to influence someone’s behavior, you can manipulate him: scare him, put him under pressure, make promises, reward him “if …”. This strategy works – at least in the short term – but it is costly. You need to manipulate more and more to get results, and you lose all intrinsic motivation on the other side. On the contrary, when you inspire your collaborators, they don’t follow you because they have to or because they’re paid to: they follow you because they want to. And that makes all the difference.
