Even if it takes a lifetime

I have always wanted to be a saint. Unfortunately when I have compared myself with the saints, I have always found that there is the same difference between the saints and me as there is between a mountain whose summit is lost in the clouds and a humble grain of sand trodden underfoot by passersby. Instead of being discouraged, I told myself: God would not make me wish for something impossible and so, in spite of my littleness, I can aim at being a saint.
