Occupation
As the Oxe is most apt for the plough, the Horse for the carte, and the hound for hunting: So ought men to chuse that occupation, and Trade of life, wherunto by nature they are most apt. As he which hath no house of his owne, wandereth here and there: So he which followeth no certaine Trade of life, must foolishly assay many sorts and chaunces.
