Don’t be shy about deleting.
There is such freedom that comes through deleting what you have just written. In fact, a lack of deleting seems to imply that you take your writing too seriously.
If you can’t figure out how a whole paragraph fits into your story or essay, then can it. Erase it forever. Don’t save it.
If you need to type it again, you’ll do it better without the old paragraph lingering around, casting disapproving glares in your direction.
