I loved Saint Josemaria Escrivas' (The Founder of Opus Dei, for those who are not familiar with him) book "The Way." The book consists of very easy to read (conversational style) tips that help us walk "The Way" to holiness. St. Josemaria gives tons and tons of tips that one can employ in every day life...tips that will slowly, but surely, make one wiser, more disciplined, and holier...and thus closer to God.
From the author's preface:
"Read these counsels slowly. Pause to meditate on these thoughts. They are things that I whisper in your ear-confiding them-as a friend, as a brother, as a father. And they are being heard by God. I won't tell you anything new. I will only stir your memory, so that some thought will arise and strike you; and so you will better your life and set out along ways of prayer and of Love. And in the end you will be a more worthy soul."
