Talking about poets, it's interesting that there's not many full-time poets in the world; most poets need a paying job (often in academia) to cover the bills. I personally think this is a Good Thing as it helps give them (us) a perspective beyond the poetry scene, and the blank page, which helps ferment more enjoyable poems.
