Dr. Thomas Arnold
One's age should be tranquil, as childhood should be playful. Hard work at either extremity of life seems out of place. At midday the sun may burn, and men labor under it; but the morning and evening should be alike calm and cheerful.
Real knowledge, like everything else of value, is not to be obtained easily. It must be worked for, studied for, thought for, and, more that all, must be prayed for.
