Pray remember what I have recommended to you, which is, to think often on God, by day, by night, in your business, and even in your diversions. He is always near you and with you; leave Him not alone. You would think it rude to leave a friend alone, who came to visit you: why then must God be neglected? Do not then forget Him, but think on Him often, adore Him continually, live and die with Him; this is the glorious employment of a Christian. In a word, this is our profession; if we do not know it, we must learn it. (The Practice of the Presence of God by Brother Lawrence)
