     When we think of leadership,  we often think of strength and power.But what are these really,  and how do they operate?

     Leadership today is not about forcing others to do things.Even if this is possible,  it is shortterm,  and

tends to produce unexpected and unwanted results.If you order someone to do something against their

will,  they may do it because they feel they have to,  but the anger they feel will do more harm in the long

term.They will also experience fear.

     Fear causes the thinking brain to shut down,  making the person unable to function at his or her best.If

they connect you with this emotion of fear,  they will become less functional around you,  and you will have succeeded in not only shooting yourself in the foot,  but possibly making a very good employee or partner unable to perform effectively.Fear does no good to leadership.

     The way we influence people in a lasting way is by our own character,  and our understanding and use of emotion.We can order someone to do something,  which may be part of the work day; or we can

employ them at the emotional level,  so they will become fully devoted to the projects and provide some of their own motivation.Today's work place is all about relationships.

     Anyone works harder in a positive environment in which they're recognized and valued as a human

being as well as a worker.Everyone produces just a bit more for someone they like.Leaders understand

the way things work.They know the pay check is not the single most important factor in the work life of

most people.

     The true strength of leadership is an inner strength that comes from the confidence of emotional

intelligence-knowing your own emotions,  and how to handle them,  and those of others.Developing your

emotional intelligence is the single best thing you can do if you want to develop your relationship with

people around you,  which is the key to the leadership skills.
