The whole company of Israel complained against Moses and Aaron there in the wilderness. The Israelites said, "Why didn’t God let us die in comfort in Egypt where we had lamb stew and all the bread we could eat? You’ve brought us out into this wilderness to starve us to death, the whole company of Israel!" Exodus 16:2-3 (TM)
People are fickle. Fame is fleeting. Public opinion can blow with the Wrigley Field wind (in one minute – out the next). Those who once loved you now hold you with suspicion. Those who were singing your praises are now making up mocking parodies like Wierd Al. Leading a team at work through a project or leading a family through vacation is challenging at best. Imagine the management task before Moses and Aaron: leading over a half-million people (plus their pets and livestock) on a camping expedition that would eventually last forty years.
Strong leadership means holding the course and doing the right thing no matter what the wind of public opinion is doing. You can still listen to the complaints and you can choose to respond appropriately. Nevertheless, leaders who run off half-cocked in response to every critical comment or each whim of the masses will eventually make decisions that are bad for everyone (and you thought public opinion was bad before).
