Think of writing first person. The use of “I,” “me,” “we” and “us” become the terms used in this point of view. It instantly feels more personal. By using “I” and looking at emotions and situations in first person, you are right inside that character’s mind. You feel what they feel, see what they see, hear what they hear, and smell what they smell.
If you're writing your first novel, try the first person.
Rewrite a couple of scenes in the first person; it will make a difference.
I write character journals, which help me to get in touch with each character. Many writers balk at this "extra" work however. :-)
