To be a true leader, one can't just talk about what needs to be done, or strategize about what should be done, or delegate solely to others what they believe must be done, one has to instead, in order to be really effective, stand in front of one's people, and make them to know, that the things that need to be accomplished, start first at the very top, and therefore one must lead by example to demonstrate that through the cooperation of teamwork and a collective focused desire, great things can be accomplished.
It isn't enough for a charismatic leader to talk the talk, that leader must also walk the walk. It isn't fair or responsible to place the entire burden and the risk on everyone else, for those that want others to risk endangerment must be willing to place their own self in some sort of peril, also, or the words that they have spoken aren't the words of a leader, but the words of a protected and coddled boss.
This doesn't mean that in a military situation, that the five-star general literally puts himself in actual harm's way, for the value of that general is so great that the risk of doing this, would be foolish, but the general must be fully aware of the risks involved for his men, and take full responsibility for such risks for his soldiers, andthe decisions that are made in the battle as planned, for those in authority, ultimately rest within that authority, and therefore they should and must thereby be held accountable for the outcome.
In the business world, leaders that request specific work that must be accomplished must put forth the same effort and diligence in their oversight of such work, as those actually doing the work, for those that are applying themselves to the task at hand, are a collective resource, that needs the guidance of an accomplished team leader, in order to effect a cohesive unit that will accomplish more working together in purpose, than any could do on their own or at cross purposes.
In the religious world, it simply isn’t good enough to preach a powerful message, if the person so preaching isn't living their life as a reflection of the message given to the flock, for that is the very definition of hypocrisy, for to ask something of others, but not make it applicable to oneself, demonstrates a hollowness of principle and has no place on any pulpit.
Another reason that one must lead from the front, and cannot lead from the back, is that the people that are being addressed have their eyes and their focused attention on the person that is in front of them, not on the person that is behind them, for they cannot see that person behind them, and besides this is a forward-thinking nation, not a backward-thinking one, and progress cannot be made without taking forward steps and those steps are made in fellowship with one's leader, because it is through that leader that barriers are broken down, goals are achieved, and headway is made.
You can't lead from the back, because your view is blocked, so get out in front, stand on unwavering fair principles, work tirelessly for it, and do the right things.
