I never know how to do spacing. Someone else told me that once.
IF NOTHING ELSE,
at the end of every 3-7th sentence, hit ENTER TWICE.
Eyes need microrests of white space between lines of text.
Most folks just don’t read a mass of words. So writing a mass of words without white space between the paragraphs is essentially writing to yourself . . . some might call it typing masturbation or some such.
Most folks try and hit ENTER twice to start a new paragraph when they start talking about something slightly to significantly different than the were talking/writing about.
Hope that helps.
As has been said . . . paragraphs are our friends.
<P>aragraphs are our friends.
