Know yourself.  Stop and look at your actions and reactions.  Think about what makes you tick.  There is a sense in which you do not fully know yourself.  You need to ask God to reveal you to yourself so that you can bring who you are to the healing grace of God and become more of what you were meant to be in Christ.  The Holy Spirit is the great revealer of the human heart and the great revealer of God.  Come to Him and let Him shape you.  The Christian life is about renewal and transformation of the Christ follower.

“For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God.  For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one knows except the Spirit of God.” 1 Corinthians 2:10-11 (NASB)
