I don't pray for anything, but I have used affirmations in the past a few times. They are really a bit more like realizations in that on some level they have already happened.
Eckhart TolleYou are here to enable the divine purpose of the Universe to unfold. That is how important you are!
Eckhart TolleUnderneath your physical and psychological form, you are one with Life itself, one with Being.
Eckhart TolleWhen you look upon another human being and feel great love toward them, or when you contemplate beauty in nature and something within you responds deeply to it, close your eyes for a moment and feel the essence of that love or that beauty within you, inseparable from who you are, your true nature. The outer form is a temporary reflection of what you are within, in your essence. That is why love and beauty can never leave you, although all outer forms will.
Eckhart Tolle
