In the realm of leadership, Nelson Mandela encapsulated it all by emphasizing that a leader must have both mind and heart, sound. If you can write or communicate well then you also got something special right there.
It is not IQ over EQ, or the other way around but it is having both. Your skill in communication as well will always help you win with EQ and IQ combined.
One leads thinking that he’s got the cleverest idea but does not have the right amount of sensitivity, self-control, empathy and not having the right motivation then this leader is leading in vain. People who follow you don’t care about what or how much you know but in how much you genuinely care. You don’t lead for you, but for your people and their interests.
