Do not think I am more than half mad.

In truth I expect great things from you, and I expect without any fear of disappointment.

You have an obstinacy of perseverance, under that calm face of yours, that will be more than a match for all obstacles in your way; indeed obstacles only make the rush of the stream the greater, if once it get by them; the very things which this minute threatened to check it, the next are but trophies in the foaming triumph of its onward course.

You can do what you will; and you will aim high.

Aim at the highest.
"_I_ am aiming as hard as I can, and so fast that I can't see whether my arrows hit.
