In work too there is an austerity. It consists in not having any preferences and in doing everything one does with interest. For one who wants to grow in self-perfection, there are no great or small tasks, none that are important or unimportant; all are equally useful for one who aspires for progress and self-mastery.
It is said that one only does well what one is interested in doing.This is true, but it is truer still that one can learn to find interest in everything one does, even in what appear to be the most insignificant chores. The secret of this attainment lies in the urge towards self-perfection. Whatever occupation or task falls to your lot, you must do it with a will to progress; whatever one does, one must not only do it as best one can but strive to do it better and better in a constant effort for perfection.
In this way everything without exception becomes interesting, from the most material chore to the most artistic and intellectual work. The scope for progress is infinite and can be applied to the smallest thing.
