It is not by regretting what is irreparable that true work is to be done, but by making the best of what we are. It is not by complaining that we have not the right tools, but by using well the tools we have. What we are, and where we are is God's providential arrangement - God's doing, though it may be man's misdoing; and the manly and the wise way is to look your disadvantages in the face, and see what can be made our of them.
