From these remarks it will be evident that, allowing only ordinary ability and opportunity, we may explain success mainly by one word and that word is WORK! WORK!! WORK!!! WORK!!!! Not transient and fitful effort, but patient, enduring, honest, unremitting and indefatigable work, into which the whole heart is put, and which, in both temporal and spiritual affairs, is the true miracle worker. Every one may avail himself of this marvellous power, if he will. There is no royal road to perfection.
