I have come across geniuses in a variety of fields. Many of them have been very poor communicators. Specifically, they jump from topic to topic without closing the loop on any one thought.  Many leaders suffer from the same issue. They don’t have the time, patience or know how to dot the i’s and cross the t’s on a thought before moving on to the next one.  Then they wonder why the people that work for them cannot follow instructions or are constantly asking for their help.
