Never be afraid of contradicting yourself:  words are always one-sided.  There is always another side–another point of view.  Your words can only state one point of view.  That may seem obvious but it is true.

Someone who reads what you have written may say, “What about this or that.  That is not true all the time?!”

Don’t get upset.  Just be aware there is always another side.  Just try to state your point of view as honestly and as accurately as possible.  That all you can do.  And do not be dismayed when someone challenges you.
