Miscalculation!

(Hannah More, "Cultivation of a Devotional Spirit")

Miscalculation of the relative value of things is one of the greatest errors of our spiritual life.

We estimate them in an inverse proportion to their value, as well as to their duration.

We lavish earnest and durable thoughts on things so trifling that they deserve little regard, so temporary that they "perish with the using;" while we bestow only slight attention on things of infinite worth; only transient thoughts on things of eternal duration.
