Period (.) ends the sentence, comma (,) breaks up the sentence. If the next sentence is closely related, end the sentence with a semi-colon (;). For every other type of break--especially those that resemble the natural and chaotic shifts of thought we all have--use an em-dash. (Oh, and put text you want to be optionally skipped in parenthesis.)
Em-dash is probably the most natural punctuation; it best matches the kinds of shifts our brain does when thinking.
