Anything that weighs upon the mind, such as a worry, a fear or a feeling of remorse, keeps the mind below the pitch at which it is meant to be. When the mind is weighed down by anything, however learned a man may be, however capable and efficient, he can work very little. Learning does not help the mind which is not in its right place. So it is seen to be with many learned people, most capable and efficient; and yet incapable of accomplishing anything important in life. This is mostly found in life, and rare is the case where it is not so.
