David - "A man after God's own Heart"

Today as i was studying about the David the Psalmist, i noted that he had the following Characteristics;-
1. Humble (Psalm 62:9)
2. Reverent (Psalm 18:3
3. Respectful (Psalm 31:9)
Trusting (Psalm 27:1
Loving and Devoted (Psalm 18:1 and Psalm 9:1)
Faithful and obedient (Psalm 23:6 & Psalm 119:34)
Repentant (Psalm 25:11)
This is how we are to live our lives. WHICH OF THESE AREAS NEED OUR GREATEST ATTENTION FOR IMPROVEMENT?

David recognized that the only good in him was the God in him (Psalm 16:2) This is my prayer to you God...if only i can have these characteristics above help me understand what i must improve on.
