Does anyone here have suggestions on how I might become a better 'explainer'?
Read some of the great authors... I personally really like L'Amour, Christie, W. Smith
They tell great stories, which is accomplished through their ability to 'explain' and draw you in to a situation... Watch how they use punctuation to 'pause' or 'enhance' an illustration or setting using only words. L'Amour is probably the best I've read, because he could 'paint a picture' using only words like no one else I can think of.
