Understand what different jobs entail. They are all different and you need great knowledge and observation here. Some require courage, others subtlety. Those that depend on integrity are easier to handle, those on artifice, harder. With the right disposition, nothing else is needed for the former; but all the care and vigilance in the world are not enough for the latter. To govern people is a demanding job, and fools and madmen more so. Twice the wit is needed to deal with someone with none. A job that requires complete dedication, has fixed hours and is repetitive is intolerable; better is one which is free from boredom and which combines variety and importance, because change is refreshing. The best are those where dependency on others is minimal. The worst, one where you are held to account, both in this world and the next.
