I have found David my servant; with my sacred oil I have anointed him. My hand will sustain him; surely my arm will strengthen him.  No enemy will subject him to tribute; no wicked man will oppress him. I will crush his foes before him and strike down his adversaries.

Wow. Put yourself in David's shoes. How blessed you would be! To have the hand of God on you so that you don't even have to worry - about anything. It gives David a lot of reasons to praise God.
