My favorite prayer, Psalm 23 (NLT):

The Lord is my shepherd;

I have all that I need.

He lets me rest in green meadows;

he leads me beside peaceful streams.

He renews my strength.

He guides me along right paths,

bringing honor to his name.

Even when I walk

through the darkest valley,

I will not be afraid,

for you are close beside me.

Your rod and your staff

protect and comfort me.

You prepare a feast for me

in the presence of my enemies.

You honor me by anointing my head with oil.

My cup overflows with blessings.

Surely your goodness and unfailing love will pursue me

all the days of me life,

and I will live in the house of the Lord 

forever.
