Do not ever read books about versification: no poet ever learnt it that way. If you are going to be a poet, it will come to you naturally and you will pick up all you need from reading poetry.
A. E. HousmanTo be a textual critic requires aptitude for thinking and willingness to think; and though it also requires other things, those things are supplements and cannot be substitutes. Knowledge is good, method is good, but one thing beyond all others is necessary; and that is to have a head, not a pumpkin, on your shoulders and brains, not pudding, in your head.
A. E. Housman
