Where nature is mighty, and therefore the victory hard, the degrees had need be, first to stay and arrest nature in time; like to him that would say over the four and twenty letters when he was angry; then to go less in quantity; as if one should, in forbearing wine, come from drinking healths, to a draught at a meal; and lastly, to discontinue altogether. But if a man have the fortitude, and resolution, to enfranchise himself at once, that is the best:

Optimus ille animi vindex laedentia pectus Vincula qui rupit, dedoluitque semel.

Neither is the ancient rule amiss, to bend nature, as a wand, to a contrary extreme, whereby to set it right, understanding it, where the contrary extreme is no vice. Let not a man force a habit upon himself, with a perpetual continuance, but with some intermission.
