Which point of view is used in this excerpt from “Advice to Youth” by Mark Twain?

Go to bed early, get up early—this is wise. Some authorities say get up with the sun; some say get up with one thing, others with another. But a lark is really the best thing to get up with. It gives you a splendid reputation with everybody to know that you get up with the lark; and if you get the right kind of lark, and work at him right, you can easily train him to get up at half past nine, every time—it’s no trick at all.
