Let this be understood, then, at starting; that the patient conquest of difficulties which rise in the regular and legitimate channels of business and enterprise is not only essential in securing the success which you seek but it is essential to that preparation of your mind, requisite for the enjoyment of your successes, and for retaining them when gained. So, day by day, and week by week; so month after month, and year after year, work on, and in that progress gain in strength and symmetry, and nerve and knowledge, that when success, patiently and bravely worked for, shall come, it may find you prepared to receive it and keep it.
