You have to persevere and fortify your pertinacity until the will to good becomes a disposition to good.
Seneca the YoungerWhat must be shall be; and that which is a necessity to him that struggles, is little more than choice to him that is willing.
Seneca the YoungerThe condition of all who are preoccupied is wretched, but most wretched is the condition of those who labor at preoccupations that are not even their own, who regulate their sleep by that of another, their walk by the pace of another, who are under orders in case of the freest things in the world-loving and hating. If these wish to know how short their life is, let them reflect how small a part of it is their own.
