Enter by the Small Rivers

Because you have asked me, my brother John, most dear to me in Christ, how to set about acquiring the treasure of knowledge, this is the advice I pass on to you: That you should choose to enter by the small rivers, and not go right away into the sea, because you should move from easy things to difficult things. (from Letter of St.Thomas Aquinas on how to study)
