Leaders get lost because of isolation, delusion, arrogance, plain stupidity, etc., but above all because they become obsessed with imposing their authority, instead of truly leading.
Leading is helping people achieve a shared vision, not telling people what to do.
It is not possible for a leader to understand and lead people when the leader's head is high in the clouds or stuck firmly up his backside (or someone else backside).
Loyalty to leadership relies on the leader having a connection with and understanding of people's needs and wishes and possibilities. Solutions to leadership challenges do not lie in the leader's needs and wishes. Leadership solutions lie in the needs and wishes of the followers, spend time with the people who you need.
The suggestion that loyalty and a following can be built by simply asking or forcing people to be loyal is not any basis for effective leadership. You can not lead buy bullying and deceiving.
Prior to expecting anyone to follow, a leader first needs to demonstrate a vision and values worthy of a following. This vision must be a common vision and not one for them selves.
A given type of leadership inevitably attracts the same type of followers. Put another way, a leadership cannot behave in any way that it asks its people not to.
For people to embrace and follow modern compassionate, honest, ethical, peaceful, and fair principles, they must see these qualities demonstrated by their leadership regularly.
People are a lot cleverer than most leaders think.
People have a much keener sense of truth than most leaders think.
People quickly lose faith in a leader who behaves as if the two previous points do not exist.
People generally have the answers which elude the leaders - they just have better things to do than help the leader to lead - like getting on with their own lives.
A leadership which screws up in a big way should come clean and admit their errors. People will generally forgive mistakes but they do not tolerate being treated like idiots by leaders.
A mistake is an opportunity to be better, and to show remorse and a lesson learned. This is how civilization progresses.
A leader should be brave enough to talk when lesser people want to fight. Anyone can resort to threats and aggression. Being aggressive is not leading. It might have been a couple of thousand years ago, but it's not now. The nature of humankind and civilization is to become more civilized. Leaders should enable not obstruct this process.
