there are a lot of people offering a lot of highfalutin opinions on the writing process.
i don't understand all the hubbub.
it's quite simple.
at least mine is.
and here it is for free no less.
i place one word to the right (my right, it's left) of the last word until i'm not sure what to do, at which point i add a comma (or in some cases, when i've really screwed up, something referred to as a partial colon, which really should be renamed), and continue on until something unrelated strikes me, at which point i use a pair of these things here "―" (or parentheses when i feel like old school) to squeeze the dumb interruption in, then pick up where i left off and continue on my merry way until i'm certain i have completed a thought―albeit a bob thought―at which point i end the mess with a period (or in those rare cases when i'm really certain i have completed a crisp, coherent thought, an exclamation point).
so put that quill in your cap and smoke it!
