@MHowell asɛnka nni ho! Great read and good points, especially this one:

If you’re a writer or an activist or anyone else engaged in critical synthesis, then the news-stories, ideas, sights and sounds you encounter are liable to tug at your attention: this is a piece of something bigger, and maybe something important.

That tug is the old call of the storyteller - that there is something vital in your words, needed by someone, somewhere, and that alone makes the tale worthwhile to tell.
