I do a fair amount of writing. In addition to sermons, there are occasional articles for local newspapers, emails and notes to parishioners and others, those 140-character epistles on Twitter (known as Tweets), and the posts that appear here.
But, true confession: I don't think that I've ever been satisfied with anything I've ever written. Ever.
In fact, if, for whatever reason, I run across old blog posts, after I cringe at finding grammatical errors or unclear writing in the pieces, I will edit them. I do it even if they're more than a decade old and unlikely to ever be read again.
This piece from PBS' Mediashift, gives ten lessons aimed at people who self-publish e-books. But they're good rules for anyone who writes things they hope others will be able to understand.
To me, #10 is the most sensible lesson of all.
