Pastor John Piper recommends settling your heart before quiet time using this acrostic:

I - "Incline my heart to your testimony..." Psalm 119:36
O - "Open my eyes that I may see wonderful things in your word." Psalm 119:18
U - "Unite my heart to fear your name." Psalm 86:11
S - "Satisfy me in the morning with your steadfast love that I may rejoice and be glad all day." Psalm 90:14
