Further, another matter which greatly interferes with tranquillity of mind is that we do not manage our impulses, as sailors do their sails, to correspond to our capacity; in our expectations we aim at things too great; then, when we fail, we blame our destiny and our fortune instead of our own folly. For he is not unfortunate who wishes to shoot with his plough and hunt the hare with his ox, nor does a malicious destiny oppose him who cannot capture deer or boar with fishing creels or drag-nets; it is through folly and stupidity that such men attempt the impossible. And self-love is chiefly to blame, which makes men eager to be first and to be victorious in everything and insatiably desirous of engaging in everything. For not only do men demand to be at the same time rich and learned and strong and convivial spirits and good company, and friends of kings and magistrates of cities, but unless they shall also have dogs and horses and quails and cocks that can win prizes, they are disconsolate.
