Some writer once made the wise recommendation: one work at a time. And there is no doubt that concentrating the mind on a single piece of work can only speed it up, intensify it and be of great benefit to creation. But is it possible to stick to this rule? Perhaps with prose. With poetry, however, the situation changes, and when the planned verses exceed a few hundred, the mind seems to beg for an escape valve into which it can pour lines and lines and experience the relief of fluidity. Without this valve, soon the unproductivity, added to the ideas that accumulate in a closed deposit, begin to torture. For the poet, practicing prose seems psychologically essential.
