Here let us learn a lesson. Do keep things distinct in your minds--not huddled and muddled by a careless thoughtlessness. Do not live a confused life, without care and discretion, running all things into one; but sort things out, and divide and distinguish between the precious and the vile. See what this is worth, and what the other is worth, and set your matters in rank and order, making some of them principal, and others of them inferior. I suggest to you young people especially that, in starting life, you say to yourselves, "What shall we live for? There is a principal thing for which we ought to live, what shall it be?" Have you turned over that question, or have you gone at it hit or miss? What are you living for? What is your principal aim? Is it going to be that of the old gentleman in Horace who said to his boy, "Get money: get it honestly, if you can; but, by all means, get money." Will you be a money-spinner? Shall coin be your principal corn? Or will you choose a life of pleasure--"a short life and a merry one," as so many fools have said to their great sorrow? Is it in dissipation that your life is to be spent? Are thistles to be your principal crop? Because there is a pleasure in looking at a Scotch thistle, do you intend to grow acres of pleasurable vice? And will you make your bed upon them when you come to die? Search and see what is worthy of being the principal object in life; and, when you have found it out, then beseech the Holy Spirit to help you to choose that one thing, and to give all your powers and faculties to the cultivation of it. The farmer, who finds that wheat ought to be his principal crop, makes it so, and lays himself out with that end in view; learn from this to have a main object, and to give your whole mind to it.
