Rules: The word any pronoun takes the place of must be totally clear and specific. Avoid vague and obscure references. Check very carefully whenever you use it or this, as both words often create reference errors.
Note: The pronoun he must take the place of a noun. In fact, he or she can never replace the possessive form of a name.
Note: While using this or that as pronouns usually creates problems, using them as demonstrative adjectives generally does not. For example, "This shows Huck's naive nature," remains unclear, but "This use of the word 'reckon' shows Huck's naive nature," makes sense. Even better, however, would be "Huck's use of the word 'reckon' shows his naive nature."
