Journalistic vs. Academic

So many challenges, so little space (or not much of a word count). That has been my main problem concerning the differences between journalistic writing and academic writing. I consider myself a long-winded person, one who is often wordy and keeps on going and going and never seems to end a sentence at a good stopping point, it is just going to go on forever it seems. Cut down on wordiness. That has been the cardinal rule up to this point. Which is a good rule, it means less work for me. What is that old adage? Less is more.
